Lance Holborn, South Dakota
This filter went in easily to my 2002 Subaru Impreza and I can feel a nice improvement in the power and sound of the engine. It just crises right up hills now and rarely downshifts. I think the extra few horsepower gained really helped this light little car.

The best air filter money can buy.

Excellent product, great price. My '02 Legacy GT is breathing easy now and it really smoothed out the acceleration. Conventional filters are no longer an option for me.
