intake manifold/tgv deletes/tih
1)currently on my04wrx intake manifold, if i change to the jdm sti intake manifold. does that mean that i do not have to buy tgv deletes to install. or is it better to buy the tgv deletes and install with the current manifold.
2)which jdm sti intake manifold will fit directly into the 04wrx head and throttle body.is it the 07+ sti models?
3)if i wanna install the aps 3" tih do i have to do tgv deletes or add spacers?or the jdm sti intake manifold will work fine?
thank you for the advice in advance.cheers
