📋 Before You Begin

• Park on level ground and put the shifter in Park.
• Open the hood and let the engine cool for 10–15 minutes if it was running.
• Locate the air filter box (air box): it’s the black plastic box connected to the large intake tube going toward the engine.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate and access the air box

• Open the hood and find the air box on the passenger side area of the engine bay (black plastic box with a big hose attached).
• Use safety glasses and nitrile gloves.

Step 2: Release the air box cover

• Look for the metal clips around the air box lid (some setups may also have a hose clamp on the intake tube).
• If your air box uses clips: flip each clip open by hand, or use a flathead screwdriver to gently pry it open.
• If there is a clamp at the lid/intake tube: loosen it using an 8mm socket with a 1/4" drive ratchet (or use the flathead screwdriver if it’s a screw-type clamp).
• Don’t force plastic tabs; they snap easily.

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

• Lift the air box lid up enough to pull the filter out (you usually don’t need to fully remove the lid).
• Pull the old filter straight out by hand.
• Use a clean shop towel to wipe loose dust/leaves out of the air box bottom. Do not push debris into the intake opening.

Step 4: Install the new air filter correctly

• Place the new filter into the lower air box, making sure it sits flat in the groove all the way around.
• Make sure the rubber seal edge is fully seated; gaps can let unfiltered air into the engine.

Step 5: Re-close and secure the air box

• Lower the air box lid back into position.
• Re-latch the clips by hand or with a flathead screwdriver if needed.
• If you loosened a clamp, tighten it using an 8mm socket with a 1/4" drive ratchet (snug, not over-tight).

✅ After Repair

• Start the engine and let it idle for 30 seconds.
• Listen for a hissing/whistling sound (can indicate the air box isn’t sealed).
• Check that the intake tube and air box lid are fully seated and all clips are latched.
