Skunk2 74mm RBC Flange to PRB Pattern Throttle Body Adapter - Honda K-Series (Universal)

The Skunk2 74mm throttle body adapter lets you install an early K (PRB) cable-driven Pro Series throttle body onto late-model K (RBC) flange intake manifolds, a must when running a Pro Series throttle body on a K-swapped vehicle with the popular RBC/RRC manifolds. It is CNC-machined from 6061 billet aluminum and anodized for corrosion resistance, with a 74mm opening, 72mm exit and a notch for the idle air control valve. Gasket and hardware are included.
