🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the hood

• Pull the hood-release handle inside the cab.
• Release the secondary hood latch at the front edge and raise the hood.
• Use the LED inspection flashlight to locate the black air-filter housing in the engine compartment.

Step 2: Clean around the housing

• Put on the safety glasses and nitrile work gloves.
• Use the soft-bristle 25mm detailing brush and portable vacuum with crevice attachment to remove loose dust from around the housing seam.
• This prevents debris from falling into the clean side of the intake.

Step 3: Release the air-box retainers

• Release the retaining clips around the air-filter housing by hand.
• Move each clip completely away from the lid.
• Don’t pry against the plastic housing with a screwdriver.
• Cold plastic clips dislike brute force.

Step 4: Lift the housing lid

• Carefully raise the housing lid enough to access the filter.
• Keep the connected intake duct and wiring relaxed. Don’t pull or twist them.
• If the lid resists, stop and use the LED inspection flashlight to check for a clip that’s still engaged.

Step 5: Remove the old filter

• Note how the old filter is positioned before lifting it out.
• Lift the filter straight upward with both hands.
• Avoid shaking loose dirt over the open housing.
• Check the old filter for heavy dust, torn pleats, moisture, oil, or rodent damage.

Step 6: Clean the lower housing

• Use the portable vacuum with crevice attachment to remove dirt and leaves from the bottom of the housing.
• Use the soft-bristle 25mm detailing brush only where needed.
• Don’t use compressed air. It can drive dirt farther into the intake system.
• Don’t drop the vacuum attachment into the intake opening.

Step 7: Install the new filter

• Place the new filter into the housing in the same orientation as the old filter.
• Run a gloved finger around the entire sealing edge.
• Confirm the seal lies flat with no folds, gaps, or trapped debris.
• The filter should sit naturally. Don’t force or trim it.

Step 8: Close the air box

• Lower the lid while watching the filter seal with the LED inspection flashlight.
• Make sure the lid’s locating tabs enter their matching slots before engaging the clips.
• Close every retaining clip by hand.
• No torque specification applies to hand-operated air-box clips.

Step 9: Perform a final inspection

• Use the LED inspection flashlight to inspect the full housing seam.
• Confirm there are no visible gaps and the filter isn’t pinched between the housing halves.
• Check that nearby hoses and electrical connectors weren’t disturbed.
• Remove every tool before closing the hood.

✅ After Repair

• 🔍 Recheck the air-box clips if the engine sounds different or the housing lid moves.
• 🧹 Inspect the filter more frequently during dusty weather or regular driving on unpaved roads.
• 💡 No dashboard reset, coding, or battery registration is needed.
