🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and find the air filter box

• Use a flashlight to locate the air filter box (a black plastic box connected to the intake tube).

Step 2: Release the air box clips

• Use your hands to unclip the metal retaining clips around the edge of the air box lid.
• If a clip is stubborn, gently assist with a flathead screwdriver. Don’t pry hard—clips can bend.

Step 3: Lift the air box lid

• Lift the lid just enough to remove the filter.
• If a wiring harness clip is holding the lid back, gently pop it free with a trim clip removal tool (a fork-shaped tool that lifts plastic clips without breaking them).

Step 4: Remove the old filter

• Pull the filter straight out.
• Use a flashlight to check how the filter sits (note the direction and how the gasket seals).

Step 5: Clean the air box sealing surface

• Use a clean rag (with nitrile gloves on) to wipe out loose dust inside the lower air box.
• Do not let debris fall down the intake opening.

Step 6: Install the new filter

• Place the new filter into the lower air box, fully seated in the same orientation as the old one.
• Make sure the filter’s rubber seal sits flat all the way around. A crooked seal can let dust in.

Step 7: Close the air box and re-latch the clips

• Lower the lid back into place, making sure it aligns evenly with the lower half.
• Snap all metal clips closed by hand.
• If you removed any harness clips, reinstall them by pressing them back in place by hand (or gently with the trim clip removal tool).

✅ After Repair

• Start the engine and let it idle for 20-30 seconds.
• Listen for hissing or whistling (a sign the air box lid isn’t sealed).
• Re-check that all clips are fully latched and the lid sits evenly.
