Dual Quad EFI made simple with the Go EFI 2×4 625HP with bright aluminum finish self-tuning system combined with the HyperFuel™ Hy-Fuel Tight-Fit In-Tank Retrofit Kit. 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 but our Go EFI 2×4 Power Adder kit can handle you guys with the bigger cubes and roots superchargers. One throttle body handles all of the brains while the second holds four 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! Bolt on two 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 touchscreen controller allows quick and easy on the fly adjustments at your fingertips!


The HyperFuel™ Hy-Fuel Tight-Fit In-Tank Retrofit Kit is a sleek miniature assembly allows you to fit a high-volume fuel system into almost any tank. This application is perfect for original or aftermarket fuel tanks as well as fuel cells with limited space. This application can also be used with a Tanks, Inc EFI tank.
