🔨 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 (air filter housing) near the engine.
• It’s the box connected to the large intake tube (the big plastic/rubber tube going toward the engine).

Step 2: Unclip the air box cover

• Put on nitrile gloves and safety glasses.
• Release the metal retaining clips around the air box by hand.
• Tip: Support the cover so it doesn’t snap back.

Step 3: Open the housing and remove the old filter

• Lift the air box cover just enough to access the filter (you usually don’t need to remove the whole cover).
• Pull the old filter straight out by hand.
• Use a flashlight to note how the filter sits (same way the new one must go in).

Step 4: Clean the air box sealing surfaces

• Use a clean microfiber towel to wipe dust out of the lower air box.
• Wipe the rim where the filter seals so the new filter can seat properly.
• Do not let debris fall into the intake tube opening.

Step 5: Install the new air filter

• Install the new filter into the lower air box by hand.
• Make sure it sits flat and fully in its channel all the way around.
• Tip: If it rocks, it’s not seated.

Step 6: Close the housing and re-latch the clips

• Lower the air box cover into position by hand.
• Re-engage each retaining clip until it snaps/locks securely.
• Use a flashlight to confirm the cover is evenly closed on all sides.

✅ After Repair

• Start the engine and let it idle for 10-20 seconds.
• Listen for air leaks (a loud hissing can mean the air box isn’t clipped closed).
• Recheck the clips and the cover alignment with a flashlight.
