Looking to convert your carbureted vehicle to Sniper EFI without the hassle of mounting an external fuel pump? Your solution is here – the Sniper EFI Master Kits featuring a Returnless Retrofit Fuel Module. Holley's Sniper EFI Self-Tuning Master Kit provides a cost-efficient upgrade to fuel injection with just four simple connections, offering enhanced engine performance, improved MPG, and easier starting. With a throttle body mounted ECU and a dual pattern bolt-on design for 4150 flange & spreadbore manifolds, this kit supports up to 650hp naturally aspirated and 575hp boosted with four 100 Lb/Hr injectors.
Tuning simplicity is our priority. The easy-to-use calibration wizard requires you to answer a few questions about your engine, initiating self-tuning without the need for a laptop. You don't need to be a computer expert to enjoy the benefits of a Sniper EFI system. The high-resolution 3.5" full-color touchscreen is your tool for tuning and gauge displays.
The Sniper Master Kit includes a fuel system with a 340LPH fuel pump in the tank, easily accomplished with basic hand tools. The Drop-in Master kits streamline plumbing by capping the regulator on the Sniper EFI throttle body with the provided -6an cap. Route the vapor guard fuel line along the chassis back to the diecast fuel hat, and your job is done.
While this kit features a returnless style fuel system, the Sniper is an Ecosystem. Seamlessly pair it with Holley's Sniper Hyperspark Ignition, Fuel Systems, Air Cleaners, Throttle Body & Digital Dash to unlock your build's full potential.
