The best thing for performance on the I6 is a tune. Check out pcmforless.com. You get better results from that. An intake also helps. I think the 77 series is the best from k&n, but there is also airaid, trueflow, afe, and i think there are other too. And finally you can get a different exhaust to help with performance too.
