If you are using the PRB cylinder head off of the K20 engine, this will allow you to route the upper radiator hose easily towards the front of the car.
Allows for a clean easy setup, and not having to deal with finding a long irregular shaped radiator hose.
This billet water neck is for the PRB K20 cylinder head only.
If you are using the complete K24 long block, you need to use the RBB Water neck for RWD K-swap setups.
Comes with 5/8" hose barb for heater hose.
