🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air filter housing

• Locate the air filter box under the hood on the engine intake side.
• Release the air box clips or loosen the retaining hardware by hand. Some lids lift straight up after the clips are released.
• Keep the housing level.

Step 2: Remove the old air filter

• Lift the old filter out of the air box.
• Note how the filter sits in the housing so the new one goes in the same way.
• If there is debris inside the box, wipe it out with a clean shop rag.

Step 3: Install the new air filter

• Place the new filter into the air box exactly as the old one sat.
• Make sure the filter edge sits flat all the way around. This is the seal that keeps unfiltered air out.
• Do not force it.

Step 4: Reinstall the air filter housing lid

• Set the lid back on the air box and line up the tabs or edges.
• Reinstall and lock all clips or fasteners by hand.
• Check the perimeter of the housing to make sure it is fully closed and even.
