I hav a 09 challenger rt, I want to change my air intake system. My question is wat is a good cai and if i shuld go with a bigger TB or bore out the factory TB? Also shuld i bother with porting my intake manifold or buy a upgraded one? I’ve had tranny work done, better clutch installed, as far as performance i got a 93 octane tune, cam, LT headers with catless mids and a borla attak muffler. Im trying to get the easy stuff dun b4 i take it to a shop to get bored and maybe stroked.
