🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the Air-Cleaner Housing

• Use the LED work light to find the black plastic air box attached to the engine's intake tube.
• Identify the metal retaining clips around the edge of its upper cover.
• Do not unplug nearby electrical connectors or loosen the intake hose.

Step 2: Release the Cover

• Wear the nitrile work gloves and release each retaining clip by hand.
• Lift the air-cleaner cover only far enough to clear the filter.
• Don't pull hard against the attached intake duct. Plastic gets less forgiving with age.

Step 3: Remove the Old Filter

• Lift the old filter straight out by hand.
• Notice its orientation before removing it completely.
• Check the dirty side for heavy dust, insects, leaves, oil, or water.
• Do not shake debris into the open clean-air side of the housing.

Step 4: Clean the Housing

• Use the damp lint-free microfiber cloth to wipe loose dirt from the lower housing and cover.
• Keep the cloth away from the intake opening beyond the filter.
• Do not use compressed air because it can drive dirt into the intake.
• Leave no cloth behind in the air box.

Step 5: Install the New Filter

• Place the new engine air filter into the housing in the same orientation as the old one.
• Ensure the rubber sealing edge sits flat inside its entire channel.
• Check every corner for folds, gaps, or trapped debris.
• Never force a filter that rocks or sits noticeably too high.

Step 6: Close and Secure the Housing

• Lower the cover squarely over the new filter.
• Make sure the cover's locating tabs engage their matching slots.
• Press the cover down gently and fasten every retaining clip by hand.
• Confirm the seam is even around the entire housing. Nissan specifically requires the cover to be seated before the clips are latched. owners.nissanusa.com
• No torque specification applies because no bolts are removed.
