🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Find the air filter box

• Open the hood and locate the large black plastic air filter box connected to the intake tube going to the engine.
• If a hose or wire is clipped to the box lid, unclip it by hand so the lid can lift.

Step 2: Release the air box clips

• Release the metal retaining clips around the air filter box lid by hand.
• If a clip is stubborn, use a flathead screwdriver to gently pry it open.
• Don’t force it; clips can bend.

Step 3: Open the air box and remove the old filter

• Lift the air box lid up just enough to access the filter (you usually don’t need to remove the whole lid).
• Pull the old filter straight out and note how it sits (the rubber edge seals against the box).

Step 4: Clean the air box (quickly)

• Use a shop towel to wipe out loose dirt in the bottom of the air box.
• If there’s debris in the bottom, use a vacuum (shop vac) to remove it.
• Do not push dirt toward the intake tube opening.

Step 5: 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 sealing edge sits flat all the way around (no corners folded).

Step 6: Close the air box and re-clip it

• Lower the lid fully so it seats evenly on the lower half of the box.
• Re-latch all metal clips by hand.
• Reattach any hose/wire clips you removed by hand.

✅ After Repair

• 🚗 Start the engine and listen for any loud hissing/whistling (can indicate the lid isn’t sealed).
