TracTuff PRB/ PRC Water Neck Flange – V2

Description

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 gasket’s footprint, an -8 ORB water bypass port, and a 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 two M6 socket head bolts, a water bypass hose fitting, and a Genuine Honda gasket.
