🔨 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 connected to the intake tube going toward the engine).

Step 2: Release the air box cover (two common setups)

• Clip style: Unhook the metal retaining clips by hand (use a flathead screwdriver gently if they’re stubborn).
• Bolt style: Remove any small bolts holding the cover using a 10mm socket and 1/4" drive ratchet.
• If there’s a hose clamp on the intake tube: Loosen it using a Phillips screwdriver or flathead screwdriver until the tube can move slightly.
• Don’t force plastic—wiggle it gently.

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

• Lift the air box lid up enough to access the filter (you usually don’t need to fully remove the lid).
• Pull the old filter straight out using gloved hands.
• Use a flashlight to note how the filter sits (so the new one goes in the same way).

Step 4: Clean the air box housing

• Wipe out loose dirt with a shop towel.
• If needed, use a hand vacuum to remove debris. (Avoid pushing dirt further down the intake.)

Step 5: Install the new engine air filter

• Place the new filter into the air box the same direction as the old one.
• Make sure it sits flat and the edges seal all the way around (no corners folded).

Step 6: Reassemble the air box

• Close the air box lid fully.
• Re-latch the clips by hand, or reinstall bolts using a 10mm socket and 1/4" drive ratchet (snug, do not over-tighten).
• If you loosened a hose clamp, tighten it using a Phillips screwdriver or flathead screwdriver until snug.

✅ After Repair

• Start the engine and let it idle for 30 seconds.
• Listen for any whistling/hissing (can mean the air box isn’t sealed or the clamp is loose).
• Double-check the air box clips/bolts are fully secured.
