TracTuff PRB/ PRC Water Neck Flange - V1
The OG billet K series water neck flange; used as an OEM replacement but better known for being used in many of my popular fabricated filler necks, fill pots, and swirl pots for the K20A, K20A2, K20A3, K20Z1 and K24A1 cylinder heads.
Beautifully machined billet 6061-T6 flange which incorporates the largest passage possible within the OEM gaskets footprint, a -8 ORB water bypass port, and a machined o-ring groove for the OEM gasket. You can choose to add a sensor port directly to the top of the flange (near the logo) or the side of the flange (under the outlet) as well as choose a standard 1.25" hose or -16 male flare fitting.
The hardware kit includes two M6 stainless steel socket head bolts, a water bypass hose fitting, and a Genuine Honda gasket.
