Frequently Asked Questions
Blackworks K2B Throttle Body Adapter - Polished. BWR Part # BWAD-TB-K2B
The Blackworks K2B Throttle Body Adapter is a billet-aluminum adapter plate designed to allow the installation of a B-series (or certain H-series) throttle body onto a K-series (RBC-style) intake manifold flange. In simpler terms: it adapts the throttle body flange pattern of one engine family (B/H) to the intake manifold flange of another (K) so you can mix components that otherwise wouldn’t bolt together.
