🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter box

• Use a flashlight and find the black plastic air box near the front/side of the engine bay with a large intake tube attached.

Step 2: Unclip the air box cover

• Use your hands to release the metal retaining clips around the air box cover.
• If a clip is stubborn, use a flat trim tool to gently pry it open. A trim tool is a flat plastic/nylon pry tool that helps release clips without breaking them.

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

• Lift the air box cover up just enough to pull the filter out (you usually don’t need to remove the whole box).
• Wear nitrile gloves and remove the old filter straight out.

Step 4: Clean the air box sealing surface

• Use a flashlight and check the bottom of the air box for leaves or heavy dirt.
• Wipe the rim (where the filter seals) with a clean rag you already have available. Good sealing prevents unfiltered air.

Step 5: Install the new filter

• Insert the new engine air filter into the air box the same way the old one came out.
• Make sure it sits flat and fully seated all the way around the edges (no corners folded).

Step 6: Close and latch the air box

• Lower the air box cover back into place.
• Use your hands to snap all the clips back on.
• Do a quick tug-check on the cover to confirm it’s latched evenly.

✅ After Repair

• Start the car and let it idle for 15–30 seconds.
• Listen for any hissing/whistling (could mean the air box isn’t sealed).
• Re-check the clips if anything sounds unusual.
