Just wondering what these are/ what they do and how they increase performance. Are they the same as itg's?? Thanks in advance
itg make air filters itb's are Individual throttle bodies. where each inlet port of the engine (i.e. one per cylinder) gets it's own throttle body (a tube with a butterfly flap in it) and it's own fuel injector. instead of one throttle body feeding a plenum chamber like most fuel injected cars have. the idea being that you can flow more air through itb's. they work and they sound fantastic.
