EFI & Engine Management

Everything EFI, featuring Holley EFI and FuelTech. Upgrade from a carburetor or outdated computer to modern electronic fuel injection with complete EFI systems, ECUs, wiring harnesses, injectors, throttle bodies, EFI intake manifolds, fuel pumps, tanks, rails, regulators, sensors and digital dashes.

Planning an EFI swap? Most conversions need an ECU, harness, injectors or a throttle-body system, and an EFI-rated fuel system. Call 713-938-4033 and we will help you put the right combination together.
