Holley Performance Products is proud to announce 4-barrel 4150 flange throttle bodies that flow 1,000 CFM of air!

If you're thinking of building either a high performance or race multi point fuel injection system for your engine, look no further than Holley for your air valve needs! Holley’s new 1,000 CFM throttle bodies share the same air entry area design used on every NASCAR Sprint Cup Series™ car! These throttle bodies are an air valve only (no injectors). Holley EFI throttle bodies are built to stand up to even the most severe usage in racing applications. They'll also look great sitting on top of your street rod or street/strip engine.

These throttle bodies will fit any standard square bore 4150 flange and flow 1,000 CFM to handle high horsepower applications. The air entry area delivers maximum velocity and accelerated air speed thanks to its exclusive CFD computer modeled design. It has integrated throttle position, idle air control, and air temperature sensors, as well as GM 700R4 and Ford transmission kickdown provisions to ensure a hassle-free install on a wide variety of vehicles. The high flow idle air control passage aids in helping large displacement engines idle. All necessary vacuum ports are integrated as well (one timed spark, two 3/8" full, and two 3/16" full). The 1.75" throttle plates are mounted to PTFE coated throttle shafts for high flow and a smooth pedal feel. The high quality die cast aluminum throttle bodies are available in either a tumble polished finish, or Holley's durable and popular Hard Core Gray™ finish so that it adds the perfect finishing touch to your engine bay!
