The Sniper EFI Quadrajet™ is here to help with classic installs, perfect for not having enough hood clearance to mount an adapter or don’t want to replace your OEM spread bore intake. Our bolt-on spread bore electronic fuel injected throttle body system does not require any additional adapters, sealing plates, or intake manifold swaps. The Sniper EFI Rochester™ Quadrajet™ (Q-Jet) system retains the same great features as the 4150 Sniper EFI version with (4) 100 lb./hr. fuel injectors, built-in timing control, 3.5" LCD touchscreen, and much more. For power, this throttle body will support up to 500 HP naturally aspirated. In addition, the Sniper EFI Rochester™ Quadrajet™ (Q-Jet) system will fit most stock air cleaners and offers multiple fuel inlet configurations that allow for a stock appearance installation. After you’ve installed your EFI, use our included 3.5" handheld to answer a few simple questions and your system will begin to self-tune with no laptop required. With the fuel kit included, you'll enure your entire system will be at peak performance.
