🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Open the hood and find the air filter housing (large plastic box on the intake tubing).
• Use safety glasses and nitrile gloves before you start.

Step 2: Open the air filter housing

• If your housing uses metal clips, release them using a flathead screwdriver (gently pry if needed).
• If your housing uses screws/bolts, loosen them with an 8mm socket, 1/4" ratchet, and 6" extension.
• Don’t force it—plastic tabs can snap.

Step 3: Remove the old air filter

• Lift the air box lid enough to slide the filter out.
• Pull the old filter straight up/out by hand and note how it sits (this helps you install the new one correctly).

Step 4: Clean the air box sealing surface

• Use a shop towel to wipe out loose dirt from the bottom of the air box.
• Wipe the sealing edge where the filter gasket sits so it seals well.
• Do not let dirt fall into the intake tube.

Step 5: Install the new air filter

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

Step 6: Close and secure the housing

• Close the air box lid fully so it’s seated evenly.
• Re-latch the clips by hand, or tighten the fasteners using the 8mm socket and 1/4" ratchet.
• If any intake duct cover clips were removed, reinstall them using a trim clip tool.
• Snug is enough—don’t over-tighten plastic.

✅ After Repair

• Start the engine and let it idle for 15–30 seconds.
• Listen for any hissing/whistling (that can mean the air box isn’t sealed).
• Do a quick visual check that all clips/fasteners are secured and the intake tube is still fully seated.
