Parti Corrispondenti K&N Purepro A5592 filtro aria

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 .

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!

I put K&N filters in every vehicle I own and have never been disappointed. I immediately noticed an increase in power and just a smoother running engine. I also have been getting 34-35 mpg since I installed the air filter.
