Stan Harris, Brandon, Florida
Fair price,fast delivery, perfect fit. I notice a measurable increase in horsepower. I will watch mileage to measure any difference. The K&N filter I had on my Chevy pickup was with me for 220,000 miles and made my 305ci engine perform like a 350. I will always put K&N filters on my cars.
