đź“‹ Before You Begin
- Park on level ground, shift to Park, and set the parking brake.
- Open the hood and locate the air box (black plastic box connected to the intake tube).
- Tip: Take a quick photo before disassembly.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Locate the air box
- Use a small flashlight to find the air box and the cover seam where it opens.
- Look for either metal clips around the edge or small screws/bolts holding the cover down.
Step 2: Open the air box (clip-style)
- If your cover uses metal clips, flip each one open by hand. If they’re tight, gently help with a flathead screwdriver.
- Lift the air box lid straight up just enough to remove the filter.
Step 3: Open the air box (screw/bolt-style)
- If your cover uses screws/bolts, loosen them with an 8mm socket and 1/4" drive ratchet.
- Set the screws/bolts aside where they can’t fall into the engine bay.
- Lift the air box lid straight up just enough to remove the filter.
Step 4: Remove the old air filter
- Pull the filter straight up and out by hand.
- Use the flashlight to look into the bottom half of the air box for leaves or heavy dirt.
- Tip: Don’t wipe dirt into the intake opening.
Step 5: Install the new air filter
- Drop the new filter into the air box in the same orientation as the old one.
- Make sure it sits flat all the way around; the rubber edge should seal evenly.
Step 6: Close and secure the air box
- Lower the lid back into place by hand, making sure it lines up with the bottom half of the box.
- Re-latch the clips by hand, or tighten the screws/bolts using an 8mm socket and 1/4" drive ratchet.
- Torque: If bolts are present, snug only (do not overtighten plastic).
âś… After Repair
- Start the engine and let it idle for 10–20 seconds.
- Listen for a loud hissing/whistling sound; that can mean the air box lid isn’t sealed.
- Recheck that all clips/bolts are secured and the lid is fully seated.
