Accel DFI Throttle Bodies
ACCEL DFI 4150 Series flange billet throttle bodies are CNC-machined to precise tolerances. The throttle blades are hand-lapped to provide minimum air leakage, while also providing excellent idle control. The stainless throttle shafts provide excellent corrosion resistance for marine use, while staged progressive linkage guarantees unparalleled drivability. Most ACCEL DFI 4150 Series flange billet throttle bodies come with integral TPS and IAC.
