Hybrid Racing Water Pump Port Block Off for K20A2/K20Z

Hybrid Racing Water Pump Port Block Off Fitting seals the factory oil cooler port on K20A2, K20Z1, and K20Z3 water pumps after removing the sandwich plate cooler. It is the proper solution for a complete oil cooler delete or for custom remote cooler setups that no longer use the factory circuit, preventing coolant leaks from the open port. Designed for both FWD and RWD applications, including swaps, this fitting permanently closes out the unused port so you can finish the plumbing cleanly.
