🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Find the engine air filter box

• Open the hood and locate the large black plastic air box on the driver-side area of the engine bay.
• Use a shop towel to wipe loose dust from the outside so it doesn’t fall in.

Step 2: Unclip the air box lid

• Locate the metal retaining clips around the edge of the air box lid.
• Release each clip by hand; if one is stubborn, gently pry it with a flat trim tool.
• Don’t force it; clips pop open.

Step 3: Open the air box and remove the old filter

• Lift the air box lid just enough to access the filter (you usually don’t need to fully remove the lid).
• Pull the old filter straight out by hand.
• Use a shop towel to cover the opening if you need a moment, so nothing drops in.

Step 4: Clean the air box (lightly)

• Use a small vacuum to remove leaves/dirt from the bottom of the air box.
• Wipe the sealing surface (where the filter edge sits) with a shop towel.
• Do not vacuum past the intake opening.

Step 5: Install the new filter

• Insert the new filter into the air box in the same orientation as the old one.
• Make sure it sits flat and fully inside the “frame” all the way around (this prevents unfiltered air leaks).

Step 6: Close and latch the air box

• Lower the lid back into place, lining up the edges.
• Snap all clips back on by hand to fully secure the lid.
• Do a quick visual check that the lid is even all the way around.

✅ After Repair

• Start the engine and let it idle for 10–20 seconds; listen for any hissing/whistling (a sign the air box isn’t sealed).
• If you hear a leak, shut the engine off and re-check that the filter is seated and the clips are fully latched.
• Optional: write the date/mileage on the filter frame with a marker for future reference.
