🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Use a flashlight and find the black plastic air box in the engine bay (this is the air filter housing).
• It’s the box connected to the big intake tube.

Step 2: Unclip the air box

• Put on nitrile gloves and safety glasses.
• Release the metal retaining clips around the air box by hand. (These “clips” are spring latches that hold the lid down.)
• Use a flashlight to confirm all clips are fully unlatched.

Step 3: Open the housing and remove the old filter

• Lift the top half of the air box lid up enough to access the filter.
• Pull the old filter straight out by hand.
• Use a clean shop towel to wipe loose dust out of the air box (do not let debris fall deeper into the intake).

Step 4: Install the new filter

• Insert the new engine air filter into the housing the same way the old one came out.
• Make sure the filter sits flat and fully seals all the way around (no corners folded).
• A crooked filter can let dirt past.

Step 5: Close and re-clip the air box

• Lower the air box lid back into place, keeping the filter from shifting.
• Snap all the metal clips back on by hand until they lock firmly.
• Use a flashlight to verify the lid is evenly seated on all sides.

✅ After Repair

• Start the engine and let it idle for 10–20 seconds.
• Listen for any hissing/whistling that could indicate the air box isn’t fully clipped.
• Recheck that every clip is latched and the housing seam looks even.
