🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the Hood

• Use your hand to release the hood latches on the outside of the hood.
• Use your hand to lift the hood and secure it with the hood prop rod.
• Use the flashlight to look at the passenger side of the engine bay for the air filter housing, also called the air box. The air box is the black plastic box that holds the engine air filter.

Step 2: Locate the Air Box Cover Clips

• Use the flashlight to find the metal spring clips around the air box cover.
• A spring clip is a small metal latch that snaps the plastic air box cover shut.
• Use your hand to release the air box cover clips by pulling them away from the cover.
• Take your time with the clips.

Step 3: Lift the Air Box Cover

• Use both hands to gently lift the air box cover upward.
• Do not pull hard on the rubber intake tube connected to the cover.
• Move the cover only enough to access the air filter underneath.
• No bolts are normally removed for this air filter service, so there is no torque spec for this step.

Step 4: Remove the Old Air Filter

• Use your hand to lift the old engine air filter straight out of the lower air box.
• Look at how the old filter sits before removing it fully. The new filter must sit the same way.
• Use nitrile gloves if the old filter is dusty or dirty.

Step 5: Clean the Air Box

• Use the flashlight to inspect the bottom of the air box for leaves, sand, or debris.
• Use a clean shop towel to wipe out loose dirt from the lower air box.
• Do not push dirt into the intake opening.
• Do not use water inside the air box.
• Keep debris away from the intake tube.

Step 6: Install the New Air Filter

• Use your hands to place the new engine air filter into the lower air box.
• Make sure the rubber sealing edge sits flat all the way around.
• The seal is the soft rubber border that keeps unfiltered air from sneaking past the filter.
• If the filter looks pinched or crooked, lift it out and reseat it before closing the cover.

Step 7: Reinstall the Air Box Cover

• Use both hands to lower the air box cover back into place.
• Make sure the cover sits evenly on the new filter.
• Use your hand to snap each metal spring clip back onto the air box cover.
• Confirm every clip is fully locked.
• No fasteners are tightened on the standard air box clips, so there is no torque spec for this step.

Step 8: Final Visual Check

• Use the flashlight to check that the air box cover is fully seated.
• Use your hand to gently wiggle the cover. It should not be loose.
• Check that no shop towel, packaging, or tools are left in the engine bay.

• 🗑️ Dispose of the old air filter with normal shop waste unless local rules require otherwise.
• 📅 Check the engine air filter more often if you drive in dusty areas, off-road, or on unpaved roads.
