🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and locate the air filter box

• Use your flashlight to find the black plastic air box on the passenger-side of the engine bay.
• The air filter sits inside this box, right where the intake tube connects.

Step 2: Unclip the air box lid

• Use your hands (with nitrile gloves) to flip open the metal retaining clips around the air box lid.
• If a clip is stuck, gently pry it with a flathead screwdriver just enough to release it.
• Don’t force it; clips can bend.

Step 3: Lift the lid and remove the old filter

• Lift the air box lid up slightly to access the filter (you usually don’t need to fully remove the lid).
• Pull the old air filter straight out.
• Use a clean shop towel to wipe out loose dust/leaves inside the lower air box.

Step 4: Install the new air filter

• Insert the new engine air filter into the lower air box.
• Make sure the rubber sealing edge sits flat all the way around so unfiltered air can’t bypass it.

Step 5: Close the air box and latch the clips

• Lower the lid back into place, making sure it aligns evenly with the bottom half.
• Use your hands to snap the clips back on.
• Do a quick visual check that the lid seam is even all the way around.

✅ After Repair
