🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Use a flashlight to find the large black plastic air box near the front of the engine bay.
• Look for metal retaining clips around the edge, and/or small fasteners depending on build.

Step 2: Unclip or unfasten the air box cover

• If your air box uses metal clips, pop them open by hand or use a flathead screwdriver (small) to gently pry them free.
• If your air box uses small bolts/screws, loosen them using an 8mm socket with a 1/4" drive ratchet.
• Don’t force it—clips should release smoothly.

Step 3: Lift the cover and remove the old air filter

• Lift the air box lid enough to access the filter. Use a shop towel to wipe loose dust from the lid edge.
• Pull the old filter straight out with gloved hands (wear nitrile gloves).
• Check the bottom of the air box for leaves/sand and wipe it out using a shop towel.

Step 4: Install the new air filter correctly

• Slide the new engine air filter into the air box in the same orientation as the old one.
• Make sure the filter sits fully down in its “seat” all the way around (no gaps).
• A crooked filter can let dirt bypass.

Step 5: Close and secure the air box

• Lower the air box lid and make sure it lines up evenly.
• Re-engage the metal clips by hand, or snug the fasteners using an 8mm socket and 1/4" drive ratchet.
• Wipe your hands and nearby surfaces with a shop towel.

Step 6: Quick final check

• Use a flashlight to verify all clips/fasteners are secure and the lid is fully closed.
• Make sure no tools or towels are left in the engine bay.

✅ After Repair

• Start your A/C—sorry—start your engine and let it idle for 10–20 seconds.
• Listen for any loud hissing/whistling that could indicate the air box isn’t sealed.
• If you do hear a hissing sound, shut it off and re-check that the lid is fully clipped/fastened.
