Dual Quad! EFI! Nothing says Muscle like 2 big 4 BBL’s on a V8. FiTech EFI has made it simple with their Go EFI 2×4 625HP self-tuning dual quad normally aspirated system. This kit is a bolt on for the most popular manifolds including the Edelbrock line of dual quad manifolds without any adapters! They fit and look like they belong there because they were designed to fit from the start. Our normally aspirated kits are good thru 625hp. One throttle body handles all of the brains while the second holds 4 additional injectors and the IAC motor for idle stability. These can also be used in cross ram and tunnel ram configurations. No boost with these, please! For boosted and high horsepower normally aspirated applications please see our Go EFI 2×4 Power Adder (Part #30064).

Bolt on 2 of these tough looking throttle bodies and drive your car as the system dials itself into the perfect calibration for all of your driving and weather conditions. If you decide you want to tune for more power or economy, the FiTech touch screen controller allows quick and easy on the fly adjustments at your fingertips!
