🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air cleaner box

• Use a flashlight to find the plastic air box with a large intake tube attached.
• Wipe loose dust off the outside using a shop towel so it won’t fall into the box when opened.

Step 2: Open the air cleaner box

• If your box uses metal latches/clips, release them with a flat-blade screwdriver (gently pry if needed).
• If your box uses screws, loosen/remove them with an 8mm socket, 1/4" drive ratchet, and 6" extension.
• Lift the top half of the air box enough to access the filter. Don’t yank on the intake tube.

Step 3: Remove the old air filter

• Pull the filter straight out by hand while wearing nitrile gloves.
• Use a flashlight to check the bottom of the air box for leaves, sand, or bugs.

Step 4: Clean the air box sealing surface

• Use a shop towel to wipe the inside edges where the filter seal sits.
• Do not let debris fall down the intake tube opening (keep the box opening facing up).

Step 5: Install the new air filter

• Place the new filter into the lower air box by hand.
• Make sure the filter sits flat and the rubber seal is fully seated all the way around.

Step 6: Close and secure the air cleaner box

• Lower the air box lid into position by hand, ensuring it doesn’t pinch the filter.
• Re-latch the clips by hand or with a flat-blade screwdriver if needed.
• If equipped with screws, reinstall and tighten with an 8mm socket and 1/4" drive ratchet until snug (do not overtighten).

Step 7: Quick final check

• Use a flashlight to confirm the lid is evenly seated and no gaps are visible.
• Make sure the intake tube connection is still seated and not twisted.

✅ After Repair

• Listen for a loud hissing/whistling sound (can mean the air box isn’t sealed).
