Stop Buying Parts One at a Time.

You found the throttle body. Then you needed a fuel pump. Then a regulator. Then the right fittings, filters, and fuel line. Three weeks and four shipping boxes later, you're still not sure everything works together. A FiTech master kit puts the entire EFI conversion in one box. Throttle body, fuel delivery, wiring harness, sensors, and all the hardware to connect it. Every component matched and ready to install. Pick your fuel system style, order one kit, and get the car running.
