🔨 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 in the engine bay (it’s connected to the intake tube that goes toward the engine).
• Put on nitrile gloves and safety glasses.

Step 2: Unclip or unscrew the air box lid

• Use a flashlight to identify the metal/plastic retaining clips around the air box lid.
• Release the clips by hand. If your lid uses a screw instead of clips, remove it with a Phillips screwdriver #2.
• If a plastic push-clip or cover is in the way, gently lift it using a trim clip tool (this tool helps pop plastic clips without breaking them).

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

• Lift the air box lid slightly (you usually don’t need to fully remove it).
• Pull the old filter straight out by hand.
• Use a shop towel to wipe out loose dust in the lower air box. Don’t push dirt into the intake tube.

Step 4: Install the new engine air filter

• Compare the new filter to the old one to confirm the same size and shape.
• Install the new filter into the lower air box, making sure it sits flat in the groove all the way around.
• If the filter has an airflow arrow, point it in the same direction as the old filter (toward the engine).

Step 5: Close and secure the air box

• Lower the air box lid back into place, ensuring it aligns evenly and doesn’t pinch the filter.
• Re-latch all clips by hand, or tighten the fastener with a Phillips screwdriver #2 (snug only—do not overtighten).
• Reinstall any plastic clips using the trim clip tool if you removed them.

✅ After Repair

• Start the engine and let it idle for 20–30 seconds.
• Listen for a whistling/hissing sound (often means the air box lid isn’t sealed).
• Do a quick visual check that all clips/fasteners are fully secured and the intake tube looks seated.
