📋 Before You Begin
- Park on level ground and shift to P.
- Make sure the vehicle is completely OFF (READY light off) and the engine is cool.
- Open the hood and support it securely.
🔨 Step-by-Step Instructions
Follow these steps in order:
Step 1: Find the air filter box
- Use a flashlight to locate the black plastic air box connected to the large intake hose near the engine.
Step 2: Unclip the air box lid
- Put on nitrile gloves and safety glasses.
- Release the metal retaining clips around the air box by hand.
- If a clip is tight, gently help it with a flat-head screwdriver (pry lightly).
- Don’t force it; the clips should pop free.
Step 3: Open the air box and remove the old filter
- Lift the air box lid upward to create enough space to remove the filter.
- Pull the old filter straight out.
- Use a flashlight to look inside the air box for leaves/dirt.
Step 4: Clean the air box sealing surface
- Use the flashlight to check the air box rim (where the filter seals).
- If debris is present, remove it carefully by hand while wearing nitrile gloves.
- Keep dirt from falling into the intake tube.
Step 5: Install the new air filter
- Slide the new engine air filter into the air box in the same orientation as the old one.
- Make sure the filter sits flat and fully in its groove (no corners folded).
Step 6: Close the air box and re-latch the clips
- Lower the air box lid back into place.
- Re-engage all clips by hand so the lid seals evenly all the way around.
- If needed, use a flat-head screwdriver to nudge a clip closed (light pressure only).
✅ After Repair
- Start the vehicle (READY on) and listen for any loud hissing/whistling that could indicate the air box isn’t sealed.
- Re-check that all clips are fully latched and the lid is sitting evenly.
- If a check engine light appears (rare), re-open and confirm the filter is seated and the lid is fully closed.
