š Before You Begin
- Park on level ground and shut the engine off.
- Open the hood and let the engine bay cool for 10-15 minutes if it was just running.
- Lay a shop rag nearby to cover the intake opening if needed.
šØ Step-by-Step Instructions
Follow these steps in order:
Step 1: Locate the airbox
- Put on nitrile gloves and safety glasses.
- The airbox is the black plastic box in the engine bay with a large intake tube attached.
Step 2: Release the airbox cover (two common setups)
- If your airbox uses Torx screws: Use a Torx T25 screwdriver to loosen the screws around the airbox lid (many are ācaptiveā and stay in the lid).
- If your airbox uses metal clips: Use a flathead screwdriver to gently pop the clips off.
- A trim clip tool is a small pry tool that helps lift clips without breaking them.
Step 3: Lift the airbox lid and remove the old filter
- Use your hands to lift the lid just enough to access the filter. Donāt force it.
- Pull the old filter straight up and out.
- Use a shop rag to wipe out loose dirt inside the airbox. Donāt push dirt into the intake.
Step 4: Install the new filter correctly
- Drop the new filter into the airbox in the same orientation as the old one.
- Make sure the filterās rubber edge is fully seated all the way around (no gaps).
Step 5: Reinstall and tighten the airbox cover
- Set the lid back into place and confirm it sits evenly.
- If you have Torx screws: Use the Torx T25 screwdriver to tighten them evenly. Tighten until snugādo not overtighten plastic.
- If you have clips: Use your hands (or a flathead screwdriver gently) to snap the clips back on.
Step 6: Final check
- Visually check that the lid is fully closed and all screws/clips are secured.
- Remove any tools/rags from the engine bay.
ā After Repair
- Start the engine and let it idle for 30 seconds.
- Listen for a hissing/whistling sound (can indicate the airbox lid isnāt sealed).
- If the engine feels rough or you hear an air leak, shut it off and re-check the filter seating and airbox lid.
