TracTuff PRB/ PRC Water Neck Flange - V2


The V2 billet K series water neck flange is a spin off of the V1 flange. Intended for the rear wheel drive (RWD) swap market but just as popular in the FWD applications that need an alternate hose routing. Very popular in many of my fabricated filler necks, fill pots, and swirl pots for the K20A, K20A2, K20A3, K20Z1 and K24A1 cylinder heads.

The neck is beautifully machined from 6061-T6. The flange incorporates the largest passage possible within the OEM gaskets footprint, a -8 ORB water bypass port, and machined o-ring groove for the OEM gasket. You can choose between a standard 1.25" hose or -16 male flare outlet fitting. 

The hardware kit includes a -8 ORB to 11/16" water bypass hose fitting, a stainless hose clamp, and two stainless M6 socket head bolts, and a Genuine Honda gasket.
