🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Release the air-cleaner housing clips

• Use the LED flashlight to inspect the edge of the air-cleaner housing.
• Release the metal retaining clips by hand. A retaining clip is a spring latch that holds the housing lid closed.
• Do not pry the clips with a screwdriver; they should release with firm hand pressure.

Step 2: Raise the housing lid

• Lift the air-cleaner housing lid by hand just far enough to access the filter.
• Move the lid gently because the intake tube and airflow-sensor wiring remain attached.
• Do not unplug the airflow sensor or loosen the intake tube for routine filter replacement.

Step 3: Remove the old filter

• Note how the old filter sits in the lower housing, then lift it straight out by hand.
• Use the LED flashlight to check for leaves, sand, or other debris in the bottom of the housing.
• Keep all debris away from the clean-air opening leading toward the engine.

Step 4: Clean the lower housing

• Use the wet/dry vacuum with crevice attachment to remove loose debris from the lower housing.
• Do not push the vacuum attachment into the intake opening.
• Do not use compressed air because it can force dirt into the intake system.
• Never wipe dirt toward the engine opening.

Step 5: Install the new filter

• Place the new panel-style engine air filter into the lower housing by hand in the same orientation as the old filter.
• Use the LED flashlight to verify that the filter’s rubber sealing edge is fully seated in the housing channel.
• Check all four corners. The filter must lie flat without folds or gaps.

Step 6: Close the housing

• Lower the air-cleaner housing lid by hand while keeping the filter seal in position.
• Make sure the lid’s locating tabs engage the lower housing correctly.
• Press the lid down evenly and secure every metal retaining clip by hand.
• No torque specification applies because the housing uses hand-operated retaining clips.

Step 7: Perform a final inspection

• Use the LED flashlight to inspect the complete seam between the upper and lower housing.
• Confirm there are no gaps and no portion of the filter seal is pinched outside the housing.
• Check that the intake tube and airflow-sensor electrical connector were not disturbed.
