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.\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTransmission provisions on throttle lever for GM TH350\/TH400 and 200R4\/700R4\u003c\/li\u003e\n\u003cli\u003eFuel pump outlet wire with built in relay to directly power the fuel pump\u003c\/li\u003e\n\u003cli\u003e(4) 100 lb.\/hr. fuel injectors and 715 CFM throttle body supporting up to 500 HP naturally aspirated\u003c\/li\u003e\n\u003cli\u003eBosch LSU 4.9 Wideband Oxygen (O2) Sensor for maximum performance on real time fuel map learning\u003c\/li\u003e\n\u003cli\u003eIncluded universal throttle, transmission kickdown bracket, and brake booster adapter\u003c\/li\u003e\n\u003cli\u003eDesigned to deliver the signature Rochester Roar at wide open throttle (WOT)\u003c\/li\u003e\n\u003cli\u003e3 ground trigger outputs to control accessories such as cooling fans, AC, etc.\u003c\/li\u003e\n\u003cli\u003e3.5” LCD handheld touchscreen for setup, tuning, gauge displays, and other viewing parameters\u003c\/li\u003e\n\u003cli\u003eBuilt in Manifold Air Pressure (MAP) and Inlet Air Temperature (IAT) sensors automatically adjust to the changing conditions\u003c\/li\u003e\n\u003cli\u003eIntegrated ignition timing control when paired with HyperSpark line of distributors and ignition components, along with Holley Dual Sync\u003c\/li\u003e\n\u003cli\u003eIncluded Holley P\/N 526-12 that includes a fuel pump, fuel pressure regulator, fuel filters, supply and return hose, hose fittings, clamps, and bulkhead fitting to return into the fuel tank\u003c\/li\u003e\n\u003cli\u003eSimple installation with only (4) wires including Battery+, Battery-, 12V switched ignition, and RPM signal\u003c\/li\u003e\n\u003cli\u003eInitial handheld calibration wizard creates a base tune with no laptop needed\u003c\/li\u003e\n\u003cli\u003eThrottle body mounted ECU for a cleaner engine bay\u003c\/li\u003e\n\u003cli\u003eFits most stock Rochester Quadrajet™ (Q-Jet) air cleaners\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eProduct Specifications:\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Details:\u003c\/strong\u003e Supports Up To 500 HP - 3.5 in.
