Holley's Sniper EFI Super Sniper 1250 is a great way to convert your blow-through carbureted turbo engine to fuel injection with just 4 simple connections required. This 4-barrel system features a dual pattern bolt on design built to fit 4150 flange & spreadbore manifolds and made for those who are looking to make big power out of their vehicle. The Super Sniper 1250 is designed specifically for high horsepower boosted applications. Super Sniper can support up to 1250HP boosted with 8 100 LB/HR Injectors. If you're going the NA route for now, but plan to potentially grow into a high-horsepower forced induction build you can still run this set up and be supported up to 700HP naturally aspirated. We want everything to be as simple as it can be for you! Sniper kits are built and designed to be installed at home in your garage or driveway with limited tools and the support of Holley's comprehensive installation manual and videos. An afternoon in the garage and you will be enjoying improved engine performance, better MPG's and easier starting. After the simple installation it's time to let your Sniper begin the self-tuning process. Our user-friendly calibration wizard allows you to just answer a few questions about your engine and the system will begin self-tuning with no laptop required. You don't have to be a computer wiz or specialize in tuning to use a Sniper EFI system! Use the high resolution 3.5" full color touchscreen for tuning and gauge displays. Sniper EFI is part of a complete ecosystem! Your new Sniper kit pair's seamlessly together with Holley's Sniper Hyperspark Ignition, Fuel System's, Air Cleaners, Throttle Body & Digital Dash to unlock the full potential of your build.
