Well. That was a know Brainer. As soon as I put the peddle to the floor, I knew that the difference in acceleration was outstanding. Thank You very much. Have not changed the cabin filter yet. JOHN PAULUS

Since I replaced the stock Toyota air filter with the K &N filter I've seen a slight difference in fuel mileage and horse power. Slight but noticeable.

I put K&Ns in all of my vehicles. Love the serviceability of the filter instead of just replacing the junk paper filter every 2 years. The only reason it didn't get 5 stars is the fact that I can hear a whistle coming from the air box now with the higher flow.
