I now own two K&N filters in my 2005 S2000 Roadster and 1988 Accord LXI. We live in the Denver area over 1 mile above sea level. Both my cars showed better responsiveness and fuel efficency after I replaced the OEM filters. The air is thinner here and the cars were showing the effects of the higher altitude. I did not even re-tune the engines for the higher altitude THANKS K&N! I am a believer! Peter, Longmont, CO

I purchased a filter for each of my 3 cars and I feel a performance boost, but most notably an improvement in the fuel economy. And, none of the filters that I replaced were even dirty, so I know that the K&N filters made the difference.
