Maintaining your 2022 Nissan Frontier's air filters is crucial for optimal engine performance, interior air quality, and vehicle longevity. This comprehensive guide covers everything from basic maintenance to performance upgrades, providing you with practical knowledge for both engine and cabin air filtration systems. Whether you're a DIY enthusiast or seeking professional insights, understanding your Frontier's air filtration needs will ensure your truck runs efficiently and your cabin environment remains healthy.

Understanding Your 2022 Nissan Frontier's Air Filtration System

The 2022 Nissan Frontier utilizes two separate air filtration systems: the engine air filter and the cabin air filter. Each serves a distinct purpose but both are essential for your vehicle's performance and your comfort. The engine air filter protects your Frontier's heart by preventing harmful contaminants from entering the combustion chambers, while the cabin air filter ensures the air you breathe inside the vehicle is free from pollutants, allergens, and debris.

Regular maintenance of both filters is not just recommended but essential for preserving your truck's performance and value. A clogged engine air filter can lead to reduced power, decreased acceleration, and lower fuel efficiency. Similarly, a dirty cabin air filter can compromise your HVAC system's effectiveness and lead to unpleasant odors circulating throughout your cabin. Understanding the location, function, and maintenance requirements of each system will help you make informed decisions about your Frontier's upkeep.

Most vehicle air filters, including those in your Frontier, are typically located in one of three common positions within the engine compartment: the right side (right front wheel well) connected by a large rubber hose to a black plastic box, the left side (left front wheel well) in a similar housing, or near the right front windshield shock absorber. Your Frontier's engine air filter is housed in a black plastic container that's easily accessible once you open the hood.

Engine Air Filter Maintenance and Replacement

The engine air filter in your 2022 Nissan Frontier plays a critical role in protecting the engine from airborne contaminants. As your truck draws in air for combustion, the filter traps dust, pollen, soot, and other particulate matter that could otherwise cause premature wear to engine components. Under normal driving conditions, Nissan recommends inspecting this filter regularly and replacing it approximately every 30,000 miles, though this interval should be shortened if you frequently drive in dusty or polluted environments.

Replacing your Frontier's engine air filter is a straightforward process that most owners can complete themselves with basic tools. Here's a step-by-step guide to proper replacement:

1. ​Preparation and Safety: Park your Frontier on a level surface, engage the parking brake, and allow the engine to cool completely. Gather your new air filter (ensure it's the correct part for your specific Frontier model), a screwdriver (if needed for your filter housing), and possibly a clean cloth for wiping away debris.

2. ​Locate and Open the Air Filter Housing: Open your hood and identify the black plastic air filter housing, which is typically located on either side of the engine bay. The housing may be secured with clips, screws, or a combination of both. For clip-style fasteners, gently pry them open. For screw-type fasteners, use the appropriate screwdriver to remove them carefully.

3. ​Remove and Inspect the Old Filter: Lift the housing cover and take out the old air filter. Examine it for accumulated dirt, debris, and damage. You can gently tap the filter to dislodge surface dirt or use compressed air to clean it from the inside out, but never wash it with water as this can damage the filter media. If the filter appears heavily clogged or damaged, replacement is necessary.

4. ​Clean the Filter Housing: Before installing the new filter, take a moment to wipe out the interior of the air filter box to remove any accumulated debris or dust that could be drawn into the engine.

5. ​Install the New Filter: Place the new filter into the housing, ensuring it sits properly and seals correctly. Most filters have an anti-reverse design feature such as a protruding plastic tab that must align with a corresponding slot in the housing. This ensures proper orientation and prevents incorrect installation.

6. ​Reassemble the Housing: Replace the housing cover and securely fasten all clips or screws. Make sure the housing is properly sealed to prevent unfiltered air from bypassing the filter.

After replacement, start your engine and listen for any unusual sounds that might indicate an improper installation. You should notice improved throttle response and potentially better fuel efficiency once the new filter is in place.

Cabin Air Filter Maintenance and Replacement

While the engine air filter protects your Frontier's powerplant, the cabin air filter ensures the air inside your vehicle remains clean and free of contaminants. This filter traps pollen, dust, exhaust soot, and other airborne particles before they enter your cabin through the HVAC system. For drivers with allergies or those who frequently travel in high-pollution areas, maintaining a fresh cabin air filter is particularly important.

The cabin air filter in your 2022 Nissan Frontier is located behind the glove box, making it slightly less accessible than the engine air filter but still manageable for a DIY replacement. Here's how to replace it:

1. ​Access the Filter Location: Begin by sitting in the passenger seat and opening the glove box. Remove the contents and look for the stops or tabs on the inner sides of the glove box that allow it to swing down further. Some models may require you to remove the glove box frame by unscrewing the support screws for full access.

2. ​Locate the Filter Compartment: Behind the glove box, you'll find the filter compartment covered by a plastic access panel. This panel may be secured with clips or a screw that needs to be removed.

3. ​Remove the Old Filter: Take out the old filter, noting the direction of airflow indicated by arrows on the filter frame. This is important for proper installation of the new filter.

4. ​Install the New Filter: Insert the new cabin air filter, ensuring the airflow arrows point in the correct direction (typically downward). Make sure the filter is securely seated in the housing.

5. ​Reassemble Components: Replace the access panel and reinstall the glove box, ensuring all fasteners are properly secured.

Nissan typically recommends replacing the cabin air filter every 15,000 miles or once a year, but if you drive in severe conditions (dusty areas, heavy traffic, or regions with high pollen counts), you might consider replacing it more frequently—some experts suggest every spring and fall for optimal air quality.

A clean cabin air filter not only improves air quality but also maintains proper airflow through your HVAC system, ensuring your heater and air conditioner work efficiently. If you notice reduced airflow from your vents, unusual odors when the HVAC system is running, or persistent allergy symptoms while driving, it's likely time to replace your cabin air filter.

Performance Air Intake Systems: Upgrading Your Frontier

For Frontier owners seeking improved performance, aftermarket cold air intake systems offer an attractive upgrade over the stock air filter. These systems are designed to increase airflow to the engine, potentially boosting horsepower and torque while enhancing engine sound under acceleration. Brands like aFe Power and K&N Engineering offer specialized intake systems specifically designed for the 2022 Nissan Frontier with its 3.8L V6 engine.

​aFe Power Momentum GT Cold Air Intake System​
This system features a 360-degree radial flow air filter with either oiled Pro 5R media (five layers of progressively finer cotton gauze) or oil-free Pro Dry S media (three layers of synthetic material). The oiled version is ideal for street and track use, while the oil-free option works well for street and light off-road applications. Both options utilize a heat-resistant XLPE polymer construction that resists heat soak and includes a clear sight window for easy filter inspection without disassembly. The system is designed to use factory mounting locations for a perfect fit and comes with stainless steel clamps and silicone couplings for secure installation.
