I drive an 06 ZX3 se with manual trans. I havn't started on the car yet but I have been looking heavily into a lot of the Cosworth Parts. My questions being does anyone know if the Cosworth CAI, Race or street exhaust, and race header/flex pipe fit my application? And finally does anyone have any of these installed and or know anything about how the cosworth parts perform? I've read some posts about what intake to buy and who has what, but of the two that had the cosworth intakes no one said much about them. Thanks for any help.
