aftermarket parts?
 

Iwas in a front end collision with my almost brand new mazda3, the stupid shop I took it to for repairs left me with an unnacceptable job. my intake manifold is damaged, so I'm looking for a new one, preferrably aftermarket, since I see now as the perfect time to start upgrading, however I can't seem to find any aftermarket manifolds, I can find intakes and such, but not exactly what I need, I've called a few shops to find out if the Mazdaspeed3 intake manifold will fit, but unfortunately it won't. Is there anyone who knows where I might find this part, either custom made, or simply prefab for the 2.3L engine??
I'm actually intending to do some more upgrades, but since this is a more crucial part, thats where I wanna get started.

This guy's running a Cosworth intake manifold on his Mazda3. I don't know if it benefits normally aspirated motors, though.

Welcome to the forum! :)

The answer is YES, it definitely works for NA...that's what is was developed for...It's part of cosworths upgrade package that makes crazy NA power on duratec 2.3L's

cool, thanks. I had heard about that, but from what I understand the throttle body doesn't fit properly, is that true? and whats the avg cost if you have any idea?

and yes the throttle body will be an issue, there is an adapter you need also , because the Cossie manifold is made for cable operated throttle bodies, not drive-by-wire ones like the mazda version of the engine...
