🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air cleaner box

• Open the hood and use a flashlight to find the large black plastic airbox connected to the intake tube (the tube leading toward the engine).

Step 2: Remove any covers blocking access (if equipped)

• If a plastic engine cover or snorkel is in the way, gently pop clips up using a flat trim tool or loosen fasteners with a 10mm socket and 1/4" ratchet.
• Set clips aside so they don’t get lost.

Step 3: Open the airbox

• Release the airbox retaining clips by hand; if a clip is tight, carefully help it with a flathead screwdriver.
• If your airbox uses screws instead of clips, loosen them with a 10mm socket and 1/4" ratchet (do not remove the entire airbox).
• Only open it enough to slide the filter out.

Step 4: Remove the old air filter

• Lift the airbox lid slightly and pull the filter straight out.
• Use a shop towel to wipe loose dust from the lower airbox half.
• Avoid wiping dirt into the intake opening.

Step 5: Install the new air filter correctly

• Insert the new filter into the airbox in the same orientation as the old one.
• Make sure the rubber sealing edge sits flat all the way around (no corners folded).
• A bad seal lets unfiltered air into the engine.

Step 6: Close and latch the airbox

• Close the airbox lid and re-engage all clips by hand.
• If you loosened screws/bolts, snug them with a 10mm socket and 1/4" ratchet (no high torque needed; do not overtighten plastic).

Step 7: Reinstall any covers/snorkels

• Reinstall any snorkel/cover you removed using the flat trim tool for clips and the 10mm socket with 1/4" ratchet for bolts.
• Do a final visual check that nothing is left loose in the engine bay.

✅ After Repair

• Start the engine and let it idle for 20–30 seconds.
• Listen for air leaks (a loud hissing/whistling can mean the airbox isn’t fully clipped).
• Take a short test drive and confirm normal throttle response and no warning lights.
