Great Product.
Ryan Seidler, Phoenix Arizona
Man I dont know where to start here. This filter has not only added more HP but it also has increased my gas millage by 6.7mpg more. I'll never again buy anything else.
Shaun Helbig, Australia
Great filter. So much better than the paper original. I get almost 10% better mileage over my old filter. Given that the old filter was fairly dirty this does not surprise me. Better engine response than before as well. A must have for your vehicle!
