🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Use a flashlight to find the black plastic air filter box on the driver-side of the engine bay.
• It’s connected to a large intake tube that runs toward the engine.

Step 2: Unclip the air box cover

• Put on nitrile gloves and safety glasses.
• Release the metal retaining clips around the air box cover by hand.
• If it resists, wiggle the clip—don’t force it.

Step 3: Open the housing and remove the old filter

• Lift the air box cover just enough to access the filter (you usually don’t need to remove the cover completely).
• Remove the old air filter straight up and out.
• Use a flashlight to check for leaves/dirt in the bottom half of the air box.

Step 4: Clean the air box sealing surface

• Use a clean shop towel to wipe out any loose dirt in the air box.
• Wipe the sealing rim where the filter sits so the new filter can seal properly.
• Don’t let debris fall into the intake opening.

Step 5: Install the new air filter

• Drop the new filter into the lower air box tray.
• Make sure it sits flat and fully seated all the way around.
• Align it the same way the old one sat (the rubber edge should seal against the box).

Step 6: Close the air box and reclip

• Lower the air box cover back into place.
• Press the cover down evenly, then snap all clips back on by hand.
• Use a flashlight to confirm the cover is not pinching the filter.

✅ After Repair

• Start the engine and let it idle for 10–20 seconds.
