Great air filter that makes the engine sound alive. Slight increase in gas milage....but who can beat the convenience of never having to buy another filter.

I noticed increased midrange and high end power with this filter, which definitley helps with merging into freeway traffic. In the two tankfuls that I have had it, I have noticed a 7% decrease in fuel efficiency, but that could just be due to my ECU adujusting to the higher air flow.
