🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter box

• Use a flashlight to find the black plastic air filter box near the front/side of the engine bay, connected to a large plastic intake tube.

Step 2: Release the airbox cover clips/screws

• Put on nitrile gloves and safety glasses.
• If your airbox uses metal clips, pop them open by hand; if they’re tight, gently help them with a flathead screwdriver (small).
• If your airbox uses screws instead of clips, loosen them with a flathead screwdriver (small) (do not remove the whole airbox).
• Tip: Don’t force plastic tabs—wiggle gently.

Step 3: Open the airbox and remove the old filter

• Lift the airbox lid enough to access the filter (some lids hinge; others lift off slightly).
• Pull the old filter straight out by hand.
• Use a clean shop towel to wipe loose dust from the inside of the airbox.
• Tip: Don’t drop dirt into the intake opening.

Step 4: Install the new air filter correctly

• Compare the new filter to the old one (same size/shape).
• Install the new filter into the airbox by hand, seating it fully in the groove all the way around.
• Make sure the filter’s rubber edge is not folded or pinched.

Step 5: Close and secure the airbox

• Close the airbox lid and confirm it sits flat and even.
• Re-lock the clips by hand, or snug the screws using a flathead screwdriver (small).
• Tip: Snug only—overtightening can crack plastic.

✅ After Repair

• Start the engine and let it idle for 10–20 seconds.
• Listen for a hissing/whistling sound (can mean the airbox lid isn’t sealed).
• Recheck the clips/screws and lid alignment if anything sounds off.
