🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Open the hood and use a flashlight to find the black plastic air box (air filter housing) near the engine.
• The air box is the plastic box the intake tube connects to (the intake tube is the large plastic/rubber tube that carries air to the engine).

Step 2: Unclip the air box lid

• Put on nitrile gloves and safety glasses.
• Release the metal retaining clips around the edge of the air box lid by hand.
• If a clip is stubborn, gently help it with a flat-blade screwdriver (don’t pry hard—clips can snap). Slow and steady prevents broken clips.

Step 3: Open the housing and remove the old filter

• Lift the air box lid up just enough to access the filter.
• Pull the old air filter straight out.
• Use a flashlight to check the bottom half of the air box for leaves or dirt.

Step 4: Clean the air box sealing surfaces

• Use a clean shop towel to wipe out loose debris in the air box.
• Wipe the sealing edge where the filter sits so the new filter can seal tightly.
• Do not let dirt fall into the intake opening.

Step 5: Install the new air filter

• Place the new filter into the air box the same way the old one came out.
• Make sure it sits flat with no corners folded and the gasket (rubber edge) is fully seated.
• If the filter has an “UP” marking, orient it the same direction as the original.

Step 6: Close the air box and re-secure the clips

• Lower the air box lid back into position.
• Re-latch all the retaining clips by hand until they snap securely into place.
• Do a quick visual check that the lid is evenly closed all the way around.

✅ After Repair

• Start the engine and let it idle for 10–20 seconds.
• Listen for any hissing/whistling that could indicate the air box lid isn’t clipped evenly.
• If you hear an air leak, shut the engine off and re-check the filter seating and clips.
