Replacing the air filter in your 2016 Nissan Altima is a critical, simple, and cost-effective maintenance task that directly impacts engine performance, fuel efficiency, and long-term reliability. This complete guide provides definitive, step-by-step instructions for checking, selecting, and changing both the engine air filter and cabin air filter, alongside vital information on why this component matters, how often to service it, and the tangible benefits of keeping it fresh. By following this practical advice, any 2016 Altima owner can ensure their vehicle runs smoothly, avoids unnecessary repairs, and maintains optimal air quality inside the cabin, all while saving money on professional service fees.
Understanding the Air Filter’s Role in Your 2016 Nissan Altima
Your 2016 Nissan Altima uses two primary air filters: the engine air filter and the cabin air filter. The engine air filter cleans the air entering the engine’s combustion chambers. It prevents dust, dirt, pollen, and other airborne contaminants from being sucked into the engine. This is vital because clean air is necessary for the proper mixing of fuel and air. A clean filter ensures the engine receives a steady, unobstructed flow of air, which is a key component of efficient combustion. The cabin air filter, often located behind the glove compartment, cleans the air that enters the interior through the heating, ventilation, and air conditioning system. It traps pollutants like dust, smog, pollen, and mold spores before they circulate inside the car. For both systems, a clean filter is fundamental to function. Neglecting either filter leads to a cascade of negative effects, from reduced engine power and higher fuel costs to poor cabin air quality and potential strain on other vehicle systems.
Specifications and Types of Air Filters for the 2016 Altima
The 2016 Nissan Altima requires specific air filter sizes and types. The engine air filter is typically a rectangular panel-style filter. The exact dimensions and part numbers can vary slightly between the 2.5-liter 4-cylinder and 3.5-liter V6 engine options, though many aftermarket filters are designed to fit both. Original Equipment Manufacturer filters from Nissan are engineered to precise specifications. Aftermarket options fall into several categories. Standard paper or cellulose filters are common and affordable, capturing most particles effectively. High-performance or high-flow filters, often made of cotton gauze or synthetic materials layered with oil, claim to increase airflow and horsepower, though the gains for daily driving are minimal. Washable and reusable filters exist but require careful maintenance. The cabin air filter is usually a pleated, rectangular filter that may contain activated charcoal. Charcoal filters add an extra layer of odor and gas fume reduction compared to standard particulate filters. Knowing your Altima’s engine size and your local driving environment will help you choose the right filter type.
Why Regular Air Filter Replacement is Non-Negotiable
The consequences of a dirty or clogged air filter are measurable and significant. For the engine, a restricted airflow forces the engine to work harder to draw in air. This disrupts the precise air-fuel ratio managed by the engine computer. The result is incomplete combustion, which leads directly to reduced fuel economy. You will visit the gas pump more often. Performance suffers, causing hesitation during acceleration, rough idling, and a general lack of power. In severe cases, excessive contaminants can bypass a torn or failed filter, causing wear on internal engine components like cylinders and piston rings. For the cabin filter, a clogged state reduces airflow from the vents, making the heating and air conditioning system work harder. This can strain the blower motor. More importantly, it fails to prevent allergens, dust, and unpleasant odors from entering the cabin, potentially affecting driver and passenger health, especially those with allergies or asthma. Regular replacement is preventative maintenance that avoids these issues.
How to Check If Your 2016 Altima Air Filter Needs Replacement
Inspecting the air filters is straightforward and requires no special tools for a visual check. For the engine air filter, open the hood and locate the air filter housing. It is a black plastic box, usually rectangular, on the driver’s or passenger’s side of the engine bay, connected to a large intake hose. The housing is secured by metal clips or screws. Release the clips or remove the screws and open the top of the housing. Lift out the filter. Hold it up to a bright light source, like the sun or a shop light. If you cannot see light passing easily through the filter material’s pleats, it is dirty. Look for an accumulation of dirt, debris, or insects. Check the filter’s rubber sealing edges for cracks or damage. Nissan’s general maintenance schedule suggests inspection every 12,000 to 15,000 miles, but driving in dusty, polluted, or high-pollen areas necessitates more frequent checks, potentially every 10,000 miles or even sooner. For the cabin air filter, the process is similar. The owner’s manual provides the exact location, but it is commonly found behind the glove box. Open the glove box, remove its contents, and look for a limit stop strap or damper on the right side. Disengage it, then squeeze the sides of the glove box to let it drop down fully. You will see a rectangular plastic cover. Open the cover, slide out the filter, and inspect it for dirt, leaves, and debris. A visibly gray or clogged filter needs changing. If you notice reduced airflow from the vents, musty odors when the fan is on, or increased window fogging, the cabin filter is a likely culprit.
Step-by-Step Guide to Replacing the 2016 Nissan Altima Engine Air Filter
Replacing the engine air filter is a simple do-it-yourself task that takes about 10 minutes. First, ensure the engine is cool and the vehicle is parked on a level surface with the parking brake engaged. Gather a new, correct air filter for a 2016 Altima, and a screwdriver if your housing uses screws instead of clips. Open the hood and secure it with the prop rod. Locate the air filter housing as described earlier. Identify the fasteners. Most 2016 Altimas use simple wing-shaped metal clips. Flip these clips open. If your model has screws, use the appropriate screwdriver to remove them. Carefully lift the top half of the air filter housing. Some intake hoses may be connected; you usually do not need to disconnect anything. Simply lift the lid enough to access the filter cavity. Remove the old air filter. Take a moment to inspect the inside of the housing for any loose debris. Use a vacuum cleaner with a hose attachment or a microfiber cloth to gently wipe out any accumulated dirt from the bottom of the housing. Never use compressed air, as it can blow debris deeper into the intake system. Place the new air filter into the housing, ensuring it sits flat and the rubber sealing edges are fully seated in the groove. The filter typically only fits one way. Carefully lower the housing lid back into place, making sure it aligns correctly. Re-engage the metal clips or reinstall the screws. Ensure all fasteners are securely closed. Do not overtighten screws. That is the complete process. Start the engine to confirm it runs normally. There is no need to reset any computer or warning light for a simple air filter change.
Step-by-Step Guide to Replacing the 2016 Nissan Altima Cabin Air Filter
Replacing the cabin air filter is equally manageable, often requiring 15-20 minutes for a first attempt. You will need the correct replacement cabin filter. Consult your owner’s manual to confirm the part type, as some models may have a carbon filter. Begin by sitting in the front passenger seat. Open the glove box door completely. Empty all items from the glove box. Look at the right interior side of the glove box. You will see a white or black plastic arm or a damper that acts as a stop to prevent the glove box from falling too far. This arm is usually attached with a small plastic pin or ball joint. Gently push or twist the end of the arm to disconnect it from its anchor point on the glove box interior. Do not force it; it is designed to pop off. Next, locate the stops on the left and right sides at the back of the glove box interior. Squeeze the sides of the glove box inward to clear these stops, allowing the entire glove box compartment to swing down and hang freely. This reveals the rear wall of the glove box assembly. You will see a rectangular plastic cover, approximately the size of a book. This cover is the cabin air filter access panel. It is held in place by small tabs. Press the tabs on the sides or top of the cover and remove it. Behind it, you will see the old cabin air filter. Slide it straight out. Note the direction of airflow arrows printed on the filter’s frame. It is crucial to install the new filter facing the same direction. Typically, the arrows should point toward the floor of the vehicle or in the direction of the cabin. If unsure, check the old filter’s orientation before removing it or consult the manual. Insert the new filter, ensuring it slides all the way into the slot. Replace the plastic cover, ensuring it clicks securely into place. Lift the glove box back into position, guiding the sides past the stops. Reattach the damper arm to its anchor point on the glove box. Close the glove box door. Turn on the vehicle and run the fan at various speeds to test airflow. The job is complete.
Tools and Supplies You Will Need
The tool requirement for this job is minimal, which is what makes it an ideal DIY project. For the engine air filter replacement, you likely need no tools at all if your housing uses clips. Having a Phillips-head or flat-head screwdriver on hand is prudent in case screws are present. A small vacuum cleaner with a crevice tool or a clean microfiber cloth is highly recommended for cleaning the housing. For the cabin air filter replacement, you need no tools. Your hands are sufficient to manipulate the glove box stops and the filter cover tabs. The only essential supply is the correct replacement filter. It is wise to purchase both the engine and cabin air filter at the same time from a reputable parts store or dealership. Keep a trash bag handy to dispose of the old, dirty filters. Wearing latex or nitrile gloves can keep your hands clean. That constitutes the entire toolkit. There is no need for advanced automotive tools, jacks, or lifts.
How to Choose the Right Replacement Air Filter: OEM vs. Aftermarket
Selecting the correct filter involves balancing cost, quality, and intended use. Original Equipment Manufacturer filters, purchased from a Nissan dealership or authorized parts retailer, guarantee an exact fit and filtration level that meets Nissan’s original specifications. They are a safe, reliable, but often more expensive choice. Aftermarket filters, from brands like FRAM, Bosch, Purolator, K&N, or WIX, offer a wide range of options. When buying aftermarket, always confirm the part is listed for a 2016 Nissan Altima with your specific engine size. Read product descriptions carefully. Standard paper filters are fine for most drivers. If you live in an area with high pollution or suffer from allergies, a cabin filter with activated carbon is a worthwhile upgrade. For the engine, high-performance washable filters from brands like K&N promise long-term savings but require periodic cleaning and re-oiling with a specific kit. Incorrect oiling can damage your engine’s mass airflow sensor. For the vast majority of 2016 Altima owners, a standard quality aftermarket filter from a trusted brand provides excellent performance and value. Always avoid generic, no-name filters of dubious quality, as a poor seal or inadequate filtration can cause damage.
Common Mistakes to Avoid During Replacement
Even simple jobs have pitfalls. Awareness prevents problems. A common error during engine air filter replacement is failing to properly seat the new filter in its housing. If the filter is crooked or the rubber gasket is not sealed, unfiltered air can bypass the filter, letting dirt into the engine. Always double-check the seal before closing the housing. Another mistake is forgetting to re-engage all the housing clips or tighten screws, which can cause the housing to open, leading to a loud sucking noise and potentially allowing water or large debris into the engine. Do not over-tighten plastic clips or screws. For the cabin filter, the most frequent error is installing the new filter in the wrong direction. The airflow arrows are there for a reason. Installing it backwards reduces efficiency and airflow. Forcing plastic tabs or the glove box damper can lead to breakage. Be gentle and follow the steps. Never use lubricants on seals or parts during this process. Do not attempt to clean and reuse a disposable paper filter; it will not be effective. Finally, do not ignore the cabin filter because it is out of sight. A clogged cabin filter strains the blower motor resistor and fan, which are more costly to replace.
Professional Replacement vs. DIY: Cost and Time Analysis
A professional replacement at a dealership or quick-lube shop for an engine air filter can cost between 50 and 100, including parts and labor. A cabin air filter replacement often costs a similar amount. The parts themselves, however, are inexpensive. A quality engine air filter retails for 15 to 30. A cabin air filter costs 20 to 40. Therefore, doing both jobs yourself costs roughly 35 to 70 in parts and about 30 minutes of your time. The professional service can cost over $150 for both. The DIY approach saves a substantial amount of money. The skill level required is beginner. The only advantage of professional service is convenience, but given the ease of access on the 2016 Altima, the DIY route is highly recommended. It also provides the satisfaction of completing basic maintenance and a firsthand look at your vehicle’s condition. If you are uncomfortable, watching a verified tutorial video specific to the 2016 Altima can build confidence. There is no special equipment or diagnostics required for a simple filter swap.
Impact on Fuel Economy, Performance, and Engine Health
A clean air filter has a direct, positive impact on your 2016 Altima’s operation. The U.S. Department of Energy states that replacing a clogged air filter can improve fuel economy by up to 10% in older vehicles, and while modern engines with computer-controlled fuel injection see a smaller percentage, the improvement is still real. In practical terms, a dirty filter can reduce mileage by 1 to 3 miles per gallon. For a 2016 Altima with an 18-gallon tank, that could mean losing 20 to 60 miles of range per tank. Performance gains are noticeable; acceleration becomes more responsive, and hesitation during merging or passing is reduced. This is because the engine can breathe easily. Long-term engine health is preserved. By ensuring only clean air enters the combustion chamber, you minimize abrasive wear on cylinder walls, pistons, and piston rings. This helps maintain engine compression and prevents oil contamination. For the cabin, a new filter restores full airflow, improving defroster and air conditioner efficiency, and provides cleaner air for occupants. The benefits are immediate and contribute to the vehicle’s longevity and resale value.
Synchronizing Air Filter Service with Other Maintenance
Air filter replacement presents an ideal opportunity to perform other simple checks and maintenance tasks. When the hood is open for the engine air filter, check other fluid levels: engine oil, coolant, brake fluid, and windshield washer fluid. Inspect the condition of the serpentine belt for cracks or glazing. Check the battery terminals for corrosion. When the glove box is down for the cabin filter, inspect the area for any lost items or debris. It is also a good reminder to check your vehicle’s maintenance schedule. The engine air filter and cabin air filter have different replacement intervals. The cabin filter is often replaced every 15,000 to 25,000 miles, but check your owner’s manual. Many owners find it convenient to replace both filters at the same time, say, once a year or every 15,000 miles, to simplify tracking. Also, consider the season; replacing the cabin filter before the pollen-heavy spring or the heating season in fall is a practical approach. Keeping a log in your glove box or a digital note with the date and mileage of the last filter change is a smart habit.
Frequently Asked Questions About the 2016 Altima Air Filter
Many questions arise regarding this component. A common one is: Can a dirty air filter cause the check engine light to come on? Yes, a severely restricted air flow can cause a lean or rich fuel mixture, potentially triggering the Mass Airflow Sensor or Oxygen Sensor to set a diagnostic trouble code and illuminate the check engine light. Another question: How often should I really change my filters if I drive mostly on highways? Highway driving is generally cleaner, so you may reach the upper end of the recommended interval. However, if you drive in dusty rural areas, frequent construction zones, or heavily polluted cities, change them more often. People also ask if they can clean an engine air filter by tapping it or using compressed air. For standard paper filters, this is not recommended. Tapping dislodges some debris but can damage the porous paper medium. Compressed air can tear the filter material. Paper filters are designed to be replaced, not cleaned. For washable performance filters, follow the manufacturer’s cleaning kit instructions explicitly. Regarding cabin filters, a question is: Will a new cabin filter make my air conditioning colder? Not directly. The air conditioning system’s cooling comes from the refrigerant. However, a clean filter allows maximum airflow over the cold evaporator core, so the air coming from the vents may feel stronger and cooler because it is not obstructed. Finally, people ask about filter warranties. Using a non-OEM filter does not void your Nissan’s new vehicle warranty, as per the Magnuson-Moss Warranty Act, provided the filter meets reasonable specifications and is installed correctly.
Recognizing Symptoms of a Failing or Clogged Air Filter
Beyond visual inspection, your vehicle exhibits symptoms when filters are due for replacement. For the engine air filter, key signs include reduced gas mileage, which you can track at the pump. The engine may feel sluggish, especially during acceleration or when climbing hills. You might notice unusual sounds, like coughing or popping from the engine, or a rough idle. In extreme cases, black smoke from the exhaust or a gasoline smell can indicate an overly rich fuel mixture due to restricted air. For the cabin air filter, the most obvious symptom is weak airflow from the dashboard vents, even when the fan is on high speed. Unusual odors, such as a musty, moldy, or dusty smell when the fan or air conditioning is activated, are a clear indicator. Increased window fogging that is difficult to clear can also point to a clogged cabin filter reducing airflow over the evaporator. If you experience unexplained allergy symptoms while driving, the cabin filter may be saturated with pollen. Addressing these symptoms promptly by checking and replacing the filters restores normal operation.
The Importance of Genuine Parts and Reliable Sources
While aftermarket filters are acceptable, sourcing them from reliable suppliers is crucial. Avoid counterfeit or extremely cheap filters from unknown online marketplaces. These may use inferior materials that collapse, tear, or have poor sealing gaskets. A failed filter can lead to costly engine repairs. Purchase from established auto parts stores, reputable online retailers, or the Nissan dealership. Check customer reviews for specific part numbers. For peace of mind, the part number for a genuine Nissan engine air filter can be cross-referenced. Using a trusted brand ensures the filter media meets minimum efficiency standards, capturing a high percentage of harmful particles without overly restricting airflow. This balance is key. For the environmentally conscious, standard paper filters are recyclable in some municipalities; check local guidelines. Investing in quality filters is investing in your vehicle’s health.
Long-Term Ownership and the Air Filter’s Role
For owners planning to keep their 2016 Nissan Altima for many years or high mileage, consistent air filter changes are a cornerstone of responsible maintenance.
