🔨 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 box in the engine bay (it’s the box connected to the large intake tube).

Step 2: Release the air box fasteners

• Use your hands to flip open the metal retaining clips around the air box cover.
• If your air box uses a screw/clip style fastener, loosen it with a Phillips #2 screwdriver (do not remove it unless it fully comes out easily).
• Tip: Take a quick photo before opening.

Step 3: Open the air box

• Lift the air box cover up just enough to pull the filter out.
• Use a clean shop towel to wipe away loose dust around the opening (don’t push dirt inside).

Step 4: Remove the old air filter

• Pull the filter straight out by hand.
• Check the bottom of the air box for leaves or dirt and wipe it out with a clean shop towel.

Step 5: Install the new air filter

• Slide the new filter into the air box in the same orientation as the old one.
• Make sure the filter sits flat and the rubber edge (gasket) seals all the way around.
• Tip: If it won’t sit flat, it’s not aligned.

Step 6: Close and secure the air box

• Lower the air box cover into place by hand.
• Snap the clips back on by hand.
• If equipped, snug the fastener with a Phillips #2 screwdriver (tighten until secure; do not over-tighten).

Step 7: Final check

• Use a flashlight to confirm the cover is fully seated and all clips are locked.
• Remove tools and the old filter from the engine bay.
