Hybrid Racing RBC FWD Coolant Port Adapter - K20Z3/K24A/K24Z

HYB-CPA-01-04 - Hybrid Racing RBC FWD Coolant Port Adapter - K20Z3/K24A/K24Z

Clean up your K-series cooling system

The factory coolant port on an RBC cylinder head is bulky and limits your hose-routing options. Hybrid Racing's FWD coolant port adapter replaces it with a compact, fully machined housing made from a single piece of 6061 aluminum and finished in black anodizing.

The threaded -16 ORB outlet works with the included hose-barb adapter for a factory-style radiator hose or with a -16 AN fitting for a complete AN-plumbed cooling system. A separate heater port lets you retain the factory heater core with the supplied threaded fitting or complete a clean heater delete with the included -8 ORB plug.
