Skunk2 Throttle Body Adapter – K-Series (RBC to PRB Pattern)

The Skunk2 Throttle Body Adapter enables seamless integration of a Honda K-Series RBC-style throttle body (or Grams Performance DBW unit) onto PRB-pattern Skunk2 intake manifolds, such as those designed for the 2002–2006 Acura RSX and Ultra Street applications. This adapter is especially useful for installations like the Ultra Street Manifold on 2006–2015 Civic Si models running a K20 or K24 engine.
