Spearhead MPG Defense Max Thrust Engine Air Filter For All Mileage Vehicles, Fits Like OEM, Restores MPG & Acceleration (MT-997)Fashion

Experience an Obvious Difference: Whether you are noticing a delay in acceleration, less than average gas mileage or own a higher mileage vehicle, our Max Thrust engine air filters will provide a clear and cost effective upgrade over stock performance

Trap 2X Dirt vs. Standard Air Filters: Our unique Hex-D pleat design creates maximum holding capacity for trapping unwanted dirt and debris without compromising airflow like standard air filters thanks to multiple layers of progressively finer filter media that allows air to flow freely even when the filter is dirty

Increased Power and Mileage up to 15K Miles: Deficient airflow can cause your engine to work twice as hard to suck in the minimum amount of air it needs to perform regularly, resulting in poorer gas mileage and lower power efficiency; Max Thrust air filters are designed to give your engine a break by delivering as much clean air as it needs to perform optimally up to 15K miles
