I've read some posts on each of the above and I'm trying to figure out which of the above gives the most HP?

Also, does anyone know of any comparison charts of the different brands of intakes?

Cold air intakes are always good. AEM Brute Force would be my choice. Or airaid. Get one that is non oiled, K&N is oiled. AEM and Airaid are much cheaper than K&N anyway. If you have a lot of money to spend you could get a higher flowing MAF but the factory one doesn't restrict much anyway.

The air intake gives you the most hp, plus it sounds great......I have a K&N, with the million mile warranty........you wash it, then oil it, and it's as like brand new.....the throttle body is a waste of money...and the mass air flow.......well, if you want to invest 350....buckeroos for one of those things.....then go ahead....but you ain't gonna get that much of a gain.......if I were you and you want more hp........then intake, then exhaust, tune, e-fans..............and so forth....

I would look at re-programing the computer. you can gain an extra 10hp with the stock parts.
