🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Find the black plastic air box on the passenger-side front of the engine bay.
• The air box is where the intake tube (the large black tube) connects.

Step 2: Release the air box cover

• Unclip the metal retaining clips on the air box by hand. If they’re tight, gently pry with a flathead screwdriver.
• If your intake tube clamp must be loosened for extra wiggle room, use an 8mm socket with a 1/4" drive ratchet and loosen it slightly (do not remove it unless needed).
• Don’t force the plastic—wiggle it.

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

• Lift the air box lid up enough to access the filter.
• Pull the old filter straight out.
• Use a microfiber towel to cover the lower air box opening if you need a moment, so nothing falls in.

Step 4: Clean the air box (quickly)

• Use a small shop vacuum to remove loose dirt/leaves from the lower half of the air box.
• Wipe the sealing surface (where the filter’s rubber edge sits) with a clean microfiber towel.
• Keep debris out of the intake tube.

Step 5: Install the new air filter

• Place the new filter into the lower air box in the same orientation as the old one.
• Make sure the filter is fully seated and the gasket edge sits flat all the way around (no pinched corners).

Step 6: Close and secure the air box

• Lower the air box lid back into place.
• Re-engage all the metal clips by hand.
• If you loosened the intake tube clamp, tighten it using an 8mm socket and 1/4" drive ratchet until snug (do not overtighten).

✅ After Repair

• Start the engine and let it idle for 10-20 seconds.
• Listen for air leaks (a loud hissing) around the air box and intake tube.
• If you hear a leak or see the lid sitting crooked, shut the engine off and re-seat the filter and clips.
