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 has also been a great option for many FWD applications that need an alternate hose routing. The flange is also used in several of my fabricated filler necks, fill pots, and swirl pots for the RWD market. The flange fits K20A, K20A2, K20A3, K20Z1, and K24A1 cylinder heads.

Machined from US milled 6061 material. The flange incorporates an o-ring groove to accept an OEM gasket, a -16 ORB outlet, and -8 ORB water bypass port. 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 the type of outlet fitting (shown below).

The hardware kit includes two M6 socket head bolts, an 11/16″ water bypass hose fitting, a clamp, and a Genuine Honda gasket.
