Easy install and noticed a difference right away. As soon as the air intake is CARB exempt, I will get it. Fantastic.
Stanley Levine, New Jersey
Better sounds, performance, and maybe a little better gas milage.
JB, Wayne, Pennsylvania
Great filter! Slight but noticeable improvement in acceleration and fuel economy. Far better made than OEM filters, no comparison! Reusability is important too, as it reduces waste and frequency of cleaning is no problem. I have recommended this brand of air filter to friends looking to improve performance and/or fuel economy. Over the long haul, the item more than pays for itself.
