🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Use a flashlight to find the air filter housing (the black plastic air box). It’s the box feeding the intake tube.
• The housing is held shut with metal clips (no bolts on most setups).

Step 2: Unclip and open the air box

• Put on nitrile gloves and safety glasses.
• Release the metal retaining clips by hand (pull them off the lid).
• Lift the top half of the air box just enough to remove the filter. Do not force it.

Step 3: Remove the old air filter

• Pull the filter straight out.
• Use a flashlight to note how the filter sits (the sealing edge should sit flat in the groove).

Step 4: Clean the air box (lightly)

• Use a clean shop towel to wipe out loose dust inside the lower half of the air box.
• Do not drop dirt into the intake opening.

Step 5: Install the new air filter

• Place the new filter into the lower air box the same way the old one came out.
• Make sure the filter’s rubber sealing edge sits evenly all the way around (no corners folded).

Step 6: Close and secure the air box

• Lower the air box lid back into place.
• Reattach all the metal clips by hand so the lid is fully sealed.
• Use a flashlight to double-check the lid is seated evenly around the perimeter.

✅ After Repair
