🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter box

• Use a flashlight and find the black plastic air box near the front/side of the engine bay with a large intake tube attached.
• Wipe loose dust off the top using a shop towel so debris doesn’t fall inside when opened.

Step 2: Open the air box

• Release the metal clips around the air box by hand (most are spring clips).
• If your air box uses screws instead of clips, remove them with a Phillips #2 screwdriver and set them aside.
• Lift the air box lid up just enough to access the filter. Don’t yank—plastic tabs can crack.
• Uncommon term: the “air box” is the plastic housing that holds the air filter.

Step 3: Remove the old filter

• Pull the old filter straight out by hand while wearing nitrile gloves.
• Use a flashlight to check the bottom of the box for leaves/sand.
• Clean the inside gently with a shop towel. Do not use compressed air aimed into the intake.

Step 4: Install the new filter

• Place the new engine air filter into the air box in the same direction as the old one.
• Make sure the filter sits flat in the track all the way around (no corners folded).
• If it won’t sit flat, it’s not aligned.

Step 5: Close and secure the air box

• Lower the lid fully and ensure it’s seated evenly.
• Re-latch all clips by hand, or reinstall screws using a Phillips #2 screwdriver until snug (do not over-tighten into plastic).
• Do a quick visual check that the intake tube connection wasn’t disturbed.

✅ After Repair

• Start the engine and let it idle for 30 seconds.
• Listen for any whistling/hissing (can mean the air box lid isn’t sealed).
• Recheck that all clips/screws are secure and the lid is fully closed.
