🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air filter housing

• Locate the engine air box on the passenger side of the engine bay.
• Release the air box cover clips by hand. No tool is usually needed.
• Lift the cover carefully without forcing the intake hose.

Step 2: Remove the old air filter

• Lift the old filter straight out of the air box.
• Note how it sits in the housing so the new one goes in the same way.
• Don’t shake debris into the intake.

Step 3: Clean the air box

• Use a clean shop rag or vacuum to remove leaves, dust, and dirt from the air box.
• Check the sealing edge for cracks, damage, or heavy debris.

Step 4: Install the new air filter

• Place the new filter into the housing in the same orientation as the old one.
• Make sure the filter sits flat all the way around the sealing edge.
• If it does not sit flat, remove it and reseat it before closing the box.

Step 5: Close and latch the housing

• Lower the air box cover into place.
• Press the cover down and re-secure all clips by hand.
• Confirm every latch is fully locked.
