Couldn't believe how restrictive the original equipment air filter was . After installing the K&N replacement , the motor seems smoother and more responsive . The great gas mileage of my Subaru appears to have improved also .

Works great, and the engine certainly feels quicker on its toes! All valuable for the added strain of big roof loads. Had a K&N on my last ride too, and they really give you bang for the buck! The filter's ridges don't run the same direction as factory, and the filter is only almost square, so installation is tricky till you figure that out!

I have always owned a K&N air filter for my various vehicles. From my truck to my car the K&N air filter provides high quality performance in any weather that is thrown at it. I live where all four seasons storm through each year and through the snow, rain, dust, and gravel roads my K&N filter has never let me down. Maintenance is simple and quick.
