🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood and locate the air box

• Open the hood and secure it.
• Use a flashlight to find the air filter housing (a black plastic box connected to the intake tube).

Step 2: Release the air box clips

• Look for the metal or plastic retaining clips around the edge of the air box lid.
• Release each clip by hand; if one is tight, gently pry it with a flat-blade screwdriver (medium).
• Tip: Don’t force clips—wiggle and lift.

Step 3: Lift the air box lid

• Carefully lift the lid just enough to remove the filter.
• Avoid pulling on the intake tube or any wiring.
• Use a shop towel to catch dust or debris.

Step 4: Remove the old air filter

• Pull the filter straight out.
• Note how it sits in the housing (which side faces up/out).

Step 5: Clean the air box sealing surface

• Use a shop towel to wipe the inside lip (the sealing edge) where the filter sits.
• Do not let dirt fall deeper into the intake path.

Step 6: Install the new air filter

• Install the new filter in the same orientation as the old one.
• Make sure the filter sits flat and fully seated all the way around.

Step 7: Close the air box and secure clips

• Lower the air box lid into position.
• Refasten all clips by hand; use the flat-blade screwdriver (medium) only if needed to help snap them in.
• Visually confirm the lid is evenly closed all the way around.
