Hybrid Racing PRB-to-ZDX Throttle Body AdapterThe Hybrid Racing PRB to ZDX throttle body adapter allows you to bolt a throttle body from an Acura ZDX engine onto an intake manifold with a "PRB" style flange. The popular large plenum Skunk2 street intake manifolds are great for power but have a drive by cable bolt pattern, making them difficult to use on a newer generation platform. This adapter allows users to bolt on the largest OEM drive by wire throttle body onto one of those intake manifolds
