Carbon Air Intake.
I am planning to get air intake modifications. I already have RPi AirScoop and aFe Air Filter. If I go for Technocraft or GruppeM air intake, Will it actually decrease my power because too many air coming into the engine?
And yes, which one is better? Technocraft or GruppeM? If I am going to do the modification, should I go for both air intake and charge pipe? or either one is enough already?
