I'm interested in getting an aftermarket intake manifold for my 03 sxt. Anybody know what companies sell them? I'm having trouble finding one. Thanks

 

First off, you cant find any because none are made aftermarket.

Second... Why?

 

Don't know much about them, was just looking for more power

 

The current intake manifold is tubular, and is the most free flowing design you will find. Its not cast like a lot of others, where porting and polishing can be beneficial.

If you want to actually make a difference in power, you will need to go turbo. Its easy as hell to find turbo anything for your car, since the EVO head and anything else turbo related will bolt right up to your engine.

Little add ons like cold air intake or bigger injectors or bigger throttle body wont help you unless you go forced induction.
