Description

Looking for something different and cool for your LS engine? The FiTech Retro LS dual quad throttle body system will really stand out in a sea of LS engines thanks to FiTech's unique sheet metal intake manifold topped with two throttle bodies! The trick intake is plumbed with fuel rails and eight injectors set up as a sequential EFI system. Thanks to FiTech's well proven self-learning technology, the 2×4 will idle smoothly and cruise at low rpm but is ready to go when you hit the pedal. This system gives your LS-based vehicle that old school carbureted look with the technology and reliability of modern EFI. Choose the model for your application needs.
