HOLLEY EFI UNIVERSAL 4 BARREL 1000 CFM 4150 THROTTLE BODY POLISHED

Holley universal 4-barrel 1000 cfm 4150 flange throttle bodies feature integrated throttle position, idle air control and intake air temperature sensors to work with your aftermarket multi-port EFI system. Their standard square bore mounting pattern is designed to fit perfectly on most intake manifolds and the stout 1,000 cfm can handle high horsepower with no problem. These units have a CFD computer-designed modeled air entry area--so maximum velocity and accelerated air speed are delivered to the engine. The high-flow idle air control passages are great for large cu. in. to aid in idle stability.

Holley universal 4-barrel 1000 cfm 4150 flange throttle bodies have an integrated GM 700R4 transmission kickdown location, as well as a kickdown lever for use with Ford transmissions. They feature all necessary vacuum ports, one timed spark, two 3/8 in. and two 3/16 in. full manifold vacuum ports. The 1.750 in. diameter throttle plates are mounted to PTFE-coated throttle shafts for high flow and smooth feel. Their high-quality die cast aluminum construction provides excellent strength while reducing weight, and they're offered in your choice of tumble polish or hard gray anodized finishes.
