I think I’ve decided on the emissions legal afr 185’s like these although I’m open to suggestions for any emissions legal heads that might be better. Anyway I’m starting to look at emissions legal intakes and fuel rails/injectors. I need to decide on the upper and lower intakes and also the kind of fuel rails I should be running for a 408w. I think I want 40lb injectors but not sure what brand. Also need to find a 90mm throttle body that will fit whatever intake I choose. Also do I need an intake with egr stuff to pass emissions or can it get by without a check engine light without them? Links would be great and thanks for the help!
