🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Open the hood and use a small flashlight to find the black plastic air box (air filter housing) near the engine bay’s front/side.
• The air box is the plastic case that holds the rectangular filter.

Step 2: Unclip/loosen the air box cover

• Look for the metal clips or screws around the edge of the air box lid.
• If your air box uses screws, loosen them with an 8mm socket and 1/4" drive ratchet or a Phillips #2 screwdriver (some are Phillips/8mm combo heads).
• If your air box uses clips, release them by hand. Wear nitrile gloves if needed for grip.
• Tip: Don’t fully remove captive screws.

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

• Lift the air box lid just enough to slide the filter out (no need to remove the whole lid).
• Pull the old filter straight out and keep it level so dirt doesn’t fall into the lower air box.

Step 4: Clean the air box sealing surface

• Use the small flashlight to check the bottom of the air box for leaves or heavy dirt.
• If you see loose debris, carefully pick it out by hand (with nitrile gloves). Avoid pushing anything into the intake tube.

Step 5: Install the new air filter

• Insert the new filter into the lower air box the same way the old one came out.
• Make sure it sits flat and the rubber edge (gasket) is fully seated all the way around.
• If the filter has an “UP” mark, keep it facing up.

Step 6: Close the air box and secure it

• Lower the air box lid and make sure it lines up evenly with the bottom half.
• Re-latch the clips by hand, or snug the screws using a 8mm socket and 1/4" drive ratchet or Phillips #2 screwdriver.
• Do not overtighten—this is plastic.

Step 7: Quick final check

• Tug lightly on the air box lid to confirm it’s secure.
• Make sure no tools are left in the engine bay.

✅ After Repair

• Start the engine and let it idle for 10-20 seconds.
• Listen for any loud hissing/whistling that could indicate the air box lid isn’t sealed.
• If you hear a leak, shut it off and re-seat the filter and lid.
