Review: Good - Good
Review: Pretty straight forward install. Now I don't attribute this to just cuz its a K&N but I noticed better throttle response on the first drive. Then when I filled my tank I noticed that the miles till empty were 25 miles higher than before I replaced the filter. So seat of the pants it feels better and wallet says it performs better. Now the old filter had unknown miles on it but looked pretty clean before I drove from Ohio to CA and when I replaced it I noted that it was filthy. So the gains could just be relate to installing a clean filter and I would have seen the same benefits from a different filter. I like the K&N because they gave me a sticker :D

Got a great deal on this filter in the warehouse deals section. It's just like brand new! Now I have two of them so, I can switch them out fast and clean and rejuvenate the old one whenever I get a chance to do so.
