Info

Put an end to mysterious air/fuel ratios, jet changes, and cold-start rough idle troubles with Holley Sniper EFI. Affordable aftermarket fuel injection is here and it couldn't be any easier to install on your vehicle. Holley Sniper EFI is a perfect match for any muscle car, classic truck, street rod, or nearly any other carbureted vehicle. Economically priced to save your hard earned money for other parts of your build; Holley Sniper EFI is a self-tuning, plug and play fuel injection system that takes all the trouble and guesswork out of your switch to modern electronic fuel injection. With over 100 years of building quality fuel systems, you can trust Holley Sniper with all your electronic fuel injection needs!

Holley Sniper EFI is packed with all the features that your car or truck needs. This throttle body fuel injection replaces any square bore or spread bore style 2-barrel carburetor. The built in ECU keeps the wiring neat and tidy with no need to run the computer and associated wiring back into the cab of the vehicle. Connect the 4 necessary wires and you're good to go. The self-learning ECU takes care of setting the baseline tune while the full touchscreen display allows you to fine tune as you please. Sniper EFI throttle bodies utilize OEM style TPS and IAC modules for dependable and serviceable use. Life is too short to hassle  with cold start issues, hesitations, flooding, and carburetor inconsistencies. Leave that old 2-barrel to rest and bring in a new era of performance, reliability, and fun with a Holley Sniper EFI system!
