🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Locate the air filter housing

• Use a flashlight to find the rectangular black plastic air box.
• Look for metal clips and/or screws holding the lid to the lower half.

Step 2: Unfasten the air box lid

• If your air box uses clips, unhook them by hand while wearing nitrile gloves.
• If your air box uses screws, loosen them with a Phillips screwdriver #2 (they often stay captured in the lid).
• Tip: Don’t force it—recheck for hidden fasteners.

Step 3: Open the housing and remove the old filter

• Lift the lid straight up (or hinge it open) by hand.
• Pull the old filter element out carefully so dirt doesn’t fall into the lower box.
• Use a flashlight to inspect the bottom of the air box for leaves or heavy dust.

Step 4: Clean the air box sealing area

• With nitrile gloves on, wipe the rim/sealing surface with your hand or a clean dry cloth you have available.
• Do not drop debris into the intake opening.

Step 5: Install the new filter (correct direction)

• Place the new filter into the lower air box the same way the old one sat.
• Make sure it sits flat and fully into the corners—no edges folded or pinched.
• Tip: A pinched filter can leak dirt past it.

Step 6: Close and secure the air box

• Close the lid evenly by hand so it meets the lower housing all the way around.
• Reattach the clips by hand, or snug the screws with a Phillips screwdriver #2 (do not overtighten).
• Do a quick tug-check on the lid to confirm it’s fully latched.

✅ After Repair

• Start the engine and let it idle for 20–30 seconds.
• Listen for any loud hissing/whistling (a sign the air box isn’t sealed).
• Recheck the clips/screws if you hear a new air-leak sound.
