- 🅿️ Park on level ground, set the parking brake, and turn the engine off.
- Open the hood and support it securely.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Locate the air filter housing
- Use a flashlight to find the black plastic air box near the front passenger-side of the engine bay.
- You’ll see metal clips around the edge holding the air box lid closed.
Step 2: Unclip the air box lid
- Release the metal clips by hand.
- If a clip is tight, gently help it with a flathead screwdriver (medium).
- Don’t pry hard—plastic tabs can crack.
Step 3: Open the air box and remove the old filter
- Lift the top half of the air box up just enough to access the filter.
- Pull the old filter straight out.
- Use a shop towel to wipe out loose dust inside the lower air box.
- Do not drop dirt into the intake tube.
Step 4: 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 sits fully flat in the tray and the edges are sealed all the way around.
Step 5: Close and reclip the air box
- Lower the air box lid back into place, lining up the edges.
- Snap all clips back on by hand.
- Give the lid a gentle tug to confirm it’s fully latched.
âś… After Repair
- Start the engine and let it idle for 10–20 seconds.
- Listen for any hissing/whistling (a sign the air box lid isn’t sealed).
- Recheck that all clips are fully secured.
