🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and find the air box

• Use safety glasses and nitrile gloves.
• Use a flashlight to locate the air filter box (a black plastic box connected to a large intake tube).

Step 2: Unclip the air box cover

• Release the retaining clips around the air box cover by hand.
• If a clip is stubborn, gently pry it with a small flathead screwdriver.
• Don’t force it; clips should pop free.

Step 3: Lift the cover and remove the old filter

• Lift the air box cover just enough to access the filter (you usually don’t need to remove the intake tube).
• Pull the old filter straight out with your hands.
• Use a flashlight to check the air box for leaves or dirt.

Step 4: Clean the air box sealing surface

• Wipe the inside edge (where the filter seals) using a clean shop towel.
• Do not let debris fall deeper into the intake path.

Step 5: Install the new filter correctly

• Install the new engine air filter into the air box by hand.
• Make sure it sits flat and fully seated in the groove all the way around.
• If the filter has an “UP” marking, keep that side facing up.

Step 6: Close the air box and secure all clips

• Lower the air box cover into place by hand.
• Snap all retaining clips back on by hand.
• Use a flashlight to confirm the cover is evenly closed (no gaps).

✅ After Repair

• Start the engine and let it idle for 20-30 seconds.
