Classic Appearance, Modern Performance
FiTech's Go EFI Classic Throttle Body System is a ready-to-run system that strays away from the programmable features and sticks to the basic functions necessary to get the best performance and economy out of your engine. This four-injector system is capable of supporting 650 HP engines, which allows you to ditch that old carburetor and advance into the reliable performance of modern EFI. This system fits 4150-square bore or spread-bore intake manifolds and the gold finish delivers that classic, old school appearance.
