📋 Before You Begin
- 🅿️ Park on level ground, shift to Park, and set the parking brake.
- 🧼 Have a shop towel ready to wipe dust inside the air box.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Open the hood and locate the air filter box
- Open the hood and find the black plastic air filter box connected to the large intake tube.
Step 2: Unclip or loosen the air box cover
- Release the metal retaining clips around the air box lid by hand.
- If your air box uses a clamp or screw, use a flathead screwdriver to loosen it.
- Don’t remove the whole air box.
Step 3: Remove the old air filter
- Lift the air box cover just enough to access the filter.
- Pull the old filter straight out.
- Use a shop towel to wipe loose dirt from the bottom of the air box.
Step 4: Install the new air filter
- Place the new filter into the air box in the same orientation as the old one.
- Make sure the filter’s rubber edge (gasket) sits flat all the way around. This prevents unfiltered air leaks.
Step 5: Close and secure the air box
- Close the air box lid fully.
- Re-latch the clips by hand, or tighten the clamp with a flathead screwdriver until snug (do not over-tighten plastic).
✅ After Repair
- ✅ Start the engine and listen for any hissing/whistling that could indicate the air box isn’t sealed.
- 🔍 Recheck that all clips/clamps are fully secured and the lid is seated evenly.
