EFI Systems

Proflow's fabricated intake manifolds are cost effective, and performance filled! These intake manifolds feature 3mm (1/8") thick 6061-T6 sheet aluminum construction with 100% TIG welds for strength and durability. The tapered intake runners are designed to increase air velocity to evenly distribute airflow to all 8 cylinders, improving throttle response and providing consistent volumetric efficiency for your engine. There is also provision for a standard GM LS map sensor to be mounted on the rear of the plenum. Our Cast EFI intake manifold is designed for street and high performance V8 These manifolds are designed to be tuned for both excellent throttle response and greater horsepower from 1500 to 6500 rpm.
