🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Use a flashlight to find the black plastic air box on the left side of the engine bay (driver side), attached to the intake tube.

Step 2: Unclip the air box lid

• Use your hands to release the metal retaining clips around the air box lid.
• If a clip is stubborn, gently pry it with a flathead screwdriver (small). Pry gently—clips can bend.
• Term: A “retaining clip” is a spring-loaded latch that holds the lid shut.

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

• Lift the air box lid up (you usually don’t need to remove any hoses).
• Pull the old filter straight out by hand.
• Use a flashlight to look for leaves/dirt in the lower half of the air box.

Step 4: Clean the air box sealing surface

• Use a clean shop towel to wipe out loose debris from the bottom of the air box.
• Do not push debris into the intake opening.

Step 5: Install the new filter

• Place the new filter into the air box the same way the old one sat (it should sit flat with no gaps).
• Use a flashlight to confirm the rubber edge is fully seated all the way around. A good seal matters most.

Step 6: Close and re-latch the air box

• Lower the lid back into place by hand, making sure it aligns evenly.
• Snap each metal clip closed by hand.
• If needed, use the flathead screwdriver (small) to help guide a clip into place (no force).

✅ After Repair

• Start the engine and let it idle for 20-30 seconds.
• Listen for any hissing/whistling (can indicate the air box lid isn’t fully clipped).
• Recheck that all clips are fully latched and the lid is sitting evenly.
