IMPROVE PERFORMANCE by changing your vehicle's air filter at least every 12,000 miles (or as recommended in your car owner's manual); to ensure your vehicle's engine has the clean and efficient air flow it needs for fast acceleration and power.
AVOID INCREASED ENGINE WEAR caused by dirty air intake filters that may allow damaging particles to get into the engine.
