TRACTUFF THROTTLE BODY ADAPTER - RBC TO PRB

Trying to run an '06-'11 Civic Si (RBC) Drive By Wire throttle body on an older manifold with the PRB/ PRC bolt pattern? Well... we've got you!  We've made small batches of these a few times now and each time they have sold simply by word of mouth. We had a few more requests recently and decided to make a little more than before and add them here and see what happens.  The manifold side of this adapter has the PRB bolt patter; found on most roots style superchargers as well as most aftermarket intake manifolds (Skunk2 Ultra Street) and the throttle body side has the RBC bolt pattern so you can run a Drive By Wire throttle body with up to a 72mm bore. Gaskets are not included so be sure to add a PRB and RBC gasket accordingly.
