The Sniper EFI Factory refurbish process starts by stripping a used or blemish Sniper EFI throttle body down to the bare casting. From there, our highly trained factory refurbish technicians flow the original fuel injectors. If any injectors fail to meet our flow standards they are replaced with good injectors. All sensors are tested to ensure they accurately report critical engine data to the ECU. Finally, the Sniper ECU and 3.5" Touch Screen handheld are tested and updated with the latest firmware. This process ensures that our factory refurbished Sniper EFI systems are just as reliable as a new unit off the shelf. We include the following new parts; wiring harnesses, coil driver, wideband oxygen sensor, fuel pressure regulator, and any fuel system components that should be included in your kit. It's perfect for any vehicle that came standard with a 2300 Holley Flange like some Fairlanes, Galaxies, Falcons, Comets, F100s, Javelins, Rebels, Mustangs, Thunderbirds, Cougars and more. It's economically priced so you can have all the benefits of EFI and still have money to finish or upgrade your ride! It also easily adapts to a square flange or Q-jet flange 4bbl intake with a Mr. Gasket adapter P/N 1933 (4150 Square Flange) or 1929MRG (Spread Bore). Bolt-on replacement for popular classic Holley Carburetors such as the 0-4412 or 0-7448. Put an end to cold start issues, hesitations, vapor lock, and flooding. Upgrade to Sniper EFI and get the tactical accuracy of EFI today!
