Each Howell TBI system includes every component you need to make the swap, along with full instructions and 23 years of EFI experience. Your system will come with a like new, remanufactured throttle body assembly, and all sensors, components, wiring harnesses, ECM, and in-line fuel pump. We include a custom calibration PROM to match your engine, and one of our intake adapter plates to match your intake manifold to the TBI unit.
