LS Gen III/IV Rectangular-Port Pro-Flo 4 4150 EFI System, 42-lb/hr Injectors by Edelbrock®

An assembled induction system and labeled harnesses combine self-learning EFI with adjustable tuning.

This Edelbrock® Pro-Flo 4 4150 system combines an assembled intake manifold, dual aluminum fuel rails and eight 42-lb/hr injectors for LS Gen III/IV Rectangular-Port cylinder heads. The 4150-style throttle-body layout retains a conventional four-barrel induction profile. The ECU uses a Bluetooth connection to the free E-Tuner 4 app for Android or iOS devices. Self-learning fuel control works alongside adjustments for air/fuel targets, ignition curve, idle speed, acceleration fuel, cooling fans and rev limit, with real-time monitoring. Clearly labeled, pre-terminated main-engine and injector/sensor harnesses simplify wiring. The package supplies an oxygen sensor, fuel-pressure sensor, throttle-position sensor, idle-air control, MAP sensor, gaskets and installation hardware. LS versions use the engine's coil-based ignition rather than a distributor.

• LS Gen III/IV Rectangular-Port configuration • Injector flow rating: 42 lb/hr • 4150-style four-barrel throttle-body layout • Assembled manifold with dual aluminum fuel rails • Bluetooth ECU and E-Tuner 4 controls • Oxygen, fuel-pressure, TPS and MAP sensors • Idle-air control and labeled pre-terminated harnesses • Fuel-pressure sensor connection: -6 AN male • Two full-time 3/8-inch vacuum ports

Notes

  • Requires a high pressure fuel system providing 43-45 or 58-60 psi of fuel pressure with a flow rating of 57 GPH (215 liter/hr.).
  • LS Gen III and IV applications require coil harness(sold separately).
  • Forced induction applications require a 2.5-bar MAP sensor.
  • This item is not eligible for any further discounts or promotional pricing.
  • This item is Oversize 3, and is excluded from free ground shipping.
