Holley just brought EFI within range!

Introducing Super Sniper EFI 2300! 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. Looking to convert your blow thru carbureted turbo engine to EFI? Look no further! Featuring four 100 pound per hour injectors, the Super Sniper 2300 can easily support up to forced induction applications up to 650 horsepower.

Did we mention the Super Sniper also has full nitrous control built-in? That's right, no need for a separate nitrous controller! Every Super Sniper EFI system also comes with a USB to CAN tuning cable, as well as free downloadable Sniper EFI Software to give you unlimited control of your engine. It's economically priced so you can have all the benefits of EFI and still have money to finish or upgrade your ride! Bolt-on replacement for popular classic Holley carburetors such as the 0-4412 or 0-7448.

Don't have a 2300 flange intake? 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). Put an end to cold start issues, hesitations, vapor lock, and flooding.

Upgrade to Sniper EFI and get the tactical accuracy of EFI today!
