🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing (air box)

• Use a small flashlight to find the black plastic box with a large intake tube attached (this is the air box).

Step 2: Unclip or loosen the air box cover

• Look for metal clips around the edge of the air box lid.
• If your air box uses clips: release them by hand while wearing work gloves.
• If your air box uses a worm-gear clamp or a retaining tab: use a flathead screwdriver to loosen just enough to lift the lid.
• Tip: Don’t remove the intake tube unless needed.

Step 3: Open the air box and remove the old filter

• Lift the lid up carefully. If it doesn’t open far, don’t force it—recheck for another clip or fastener.
• Pull the old filter straight out by hand while wearing work gloves.
• Use a small flashlight to inspect the inside of the air box for leaves or dirt.

Step 4: Clean the air box sealing surface (lightly)

• Use your work gloves to pick out any large debris.
• If there’s loose dust, wipe the air box edge (where the filter seals) with a clean, dry cloth you already have available.
• Tip: Don’t let debris fall into the intake opening.

Step 5: Install the new engine air filter

• Place the new filter into the air box in the same orientation as the old one.
• Make sure the filter sits flat and fully in its track so it can seal (no corners sticking up).
• Use a small flashlight to confirm the filter’s gasket edge is evenly seated all the way around.

Step 6: Close and secure the air box

• Lower the air box lid back into place.
• Re-latch all clips by hand while wearing work gloves, or snug any loosened clamp using a flathead screwdriver.
• Do a quick tug test on the lid to confirm it’s locked down and not crooked.

Step 7: Final visual check

• Use a small flashlight to confirm no tools are left in the engine bay.
• Make sure the intake tube connection looks seated and straight.

✅ After Repair

• Listen for a loud hissing/whistling sound (can indicate the air box isn’t sealed).
• If you hear anything unusual, shut the engine off and re-check the lid seating and clips.
• Write down the mileage/date so you know when it was last replaced.
