I first used a K&N air filter in my 1996 Honda Accord with great results. I then followed with one in my supercharged Audi A6 and noticed a significant difference in performance. when I put one in my Subaru Outback with 150,000m on it that I bought from my friend, it was like the engine came back to life! It ran smoother and I got better gas mileage and the engine just had more power that I could feel.These babies are worth every penny.
