saying the correct aftermarket intake does not increase HP or TQ on a forced induction engine is wrong in every way. With no other modifications to the engine or PCM.
you one of those guys that swears off exhaust scavenging too I bet? Yes in the wrong application (low displacement low compression motors) a HUGE exhaust and HUGE intake filter will create negative gains and decrease longevity of your engine. In my experience ,any forced induction motor will make significant gains with a properly engineered intake and/or exhaust system used in sync.
AFEs CAI system with headers and full exhaust, plus a proper tune we're looking at near 500RWHP from these 3.5l TT engines
