TracTuff PRB/ PRC Water Neck Flange - V2


This billet K series water neck flange is a spin off of the V1 flange and is used in a number of RWD (Rear Wheel Drive) applications using for the K20A, K20A2, K20Z1 and K24A1 engines/ cylinder heads. The flange is also used as a base in several RWD filler necks, fill pots, and swirl pots. 

The neck is beautifully machined 6061-T6 flange that incorporates the largest port possible within the OEM gaskets footprint, a 1/2" NPT water bypass port, and machined o-ring groove for the OEM gasket. You can choose to have a 1/8" NPT sensor port added directly to the top of the neck (near the logo) or the side (under the outlet). The outlet itself can be configured for standard hose (1.25" OD) or -16 male flare. The hardware kit includes a 5/8" hose fitting, a plug, two stainless M6 socket head bolts, and a Genuine Honda gasket.
