Replacing your Subaru Forester’s engine air filter is a simple yet essential maintenance task that can significantly improve your vehicle’s performance and fuel efficiency. This step-by-step guide will guide you through the process, providing clear instructions and helpful tips.

Materials You’ll Need:

• New engine air filter (Subaru part number 16546AA12A)
• Clean rags or paper towels
• Screwdriver or ratchet wrench

Step 1: Locate the Engine Air Filter Housing

Open the hood and locate the black plastic housing on the right side of the engine, near the firewall. This is the engine air filter housing.

Step 2: Remove the Housing

• Use a screwdriver or ratchet wrench to loosen the two screws or bolts that secure the housing lid.
• Carefully lift the lid straight up and out of the housing.

Step 3: Remove the Old Air Filter

• Grip the old air filter by its edges and gently pull it straight up and out of the housing.
• Inspect the old filter for any signs of dirt, debris, or damage.

Step 4: Clean the Housing

• Use a clean rag or paper towel to wipe away any loose dirt or debris from the inside of the housing.
• If necessary, use a vacuum cleaner to remove any stubborn particles.

Step 5: Install the New Air Filter

• Align the new air filter with the housing and carefully insert it into place.
• Ensure that the filter is fully seated and flush with the housing.

Step 6: Replace the Housing Lid

• Place the housing lid back on top of the housing and align it with the screw holes.
• Tighten the screws or bolts securely, but do not overtighten.

Step 7: Reset the Maintenance Indicator (Optional)

• If your Forester has a maintenance indicator light, you may need to reset it after replacing the air filter.
• Consult your owner’s manual for specific instructions on how to do this.

Benefits of Replacing Your Engine Air Filter

• Improved Engine Performance: A clean air filter allows for better airflow to the engine, resulting in increased power and acceleration.
• Enhanced Fuel Efficiency: A clogged air filter restricts airflow, causing the engine to work harder and consume more fuel.
• Reduced Emissions: A clean air filter helps trap harmful pollutants, reducing the amount of emissions released into the environment.
• Extended Engine Life: By preventing dirt and debris from entering the engine, a clean air filter helps prolong its lifespan.
