🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Use a flashlight to locate the air filter housing (air box) in the engine bay.
• It’s the rectangular black plastic box with metal retaining clips around the edge.

Step 2: Unclip the air box lid

• Use your hands (and a flashlight if needed) to find the metal clips on the air box.
• Flip each clip open. They should pop free with firm finger pressure.
• Tip: Support the lid so it doesn’t snap back.

Step 3: Open the housing and remove the old filter

• Lift the air box lid just enough to access the filter. Use a flashlight to see the filter edges.
• Pull the old filter straight out by the edge.
• Use a shop towel to gently wipe out loose dirt inside the lower air box.

Step 4: Install the new air filter

• Place the new filter into the lower air box.
• Make sure the filter sits flat all the way around (no corners folded or lifted).
• Tip: If it won’t sit flat, it’s not seated.

Step 5: Close the housing and re-latch the clips

• Lower the air box lid back into place.
• Use your hands to snap each retaining clip closed.
• Use a flashlight to check the lid gap—there should be an even seal all around.

✅ After Repair
