Hybrid Racing RBC Coolant Port Adapter - K20Z3, K24A & K24Z7 (FWD)

The factory coolant port on an RBC head is bulky, ugly, and locks you into hose routing you probably don't want. If you're tucking a bay, moving to AN plumbing, or just tired of looking at the stock piece, this coolant port adapter replaces it with something compact and machined that puts you in control of where your hoses go. It's cut from a single piece of 6061 aluminum, finished in black anodize, and it gives you a -16 ORB outlet you can run either way, factory-style radiator hose or full AN.

FWD Applications, RWD Has Its Own Version

This adapter is built for front-wheel-drive applications. If you're putting one of these engines into a rear-wheel-drive swap, the coolant routing is different and we make a separate adapter for RWD.

Keep Your Heater Or Do A Clean Heater Delete

Keeping the heater? Use the supplied threaded fitting and your factory heater core stays connected. Doing a heater delete? Cap the port with the included -8 ORB plug. Both options ship in the box.

Run Factory Hoses Or Go Full AN

The outlet is a threaded -16 ORB. Use the included -16AN to hose barb adapter for standard factory-style radiator hoses, or thread in a -16 AN fitting and plumb the entire cooling system in AN line.

Machined For Flow, Not Just For Looks

The internal coolant passage is fully machined rather than left as-cast, so coolant moves through the housing smoothly instead of hitting rough surfaces and restrictions.

  • Stamped steel gasket
  • Mounting hardware
