- RBC Inatake Manifold to K-Tuned 80mm Throttle body
* The adpaters are O-ring sealed so there is no need for gasket between adapter or manifold
* Confirm that the 80mm TB you are using has a gasket
These are the same plates that come with our popular 80mm RBC Throttlebody Kit. The 2 piece adapter plates allow an 80mm TB to be used on a RBC Intake Manifold. We are now offering them separately for those wanting to run our Domestic Style Throttle Body or other aftermarket options.
By using a specialized set of billet adapters we have made it possible to port out the TB opening including the IACV (Idle Air Control Valve) section on the RBC manifold. This porting increases the size of the TB opening and allows an 80mm TB to breathe perfectly through the newly ported off-round hole.
