TracTuff PRB/ PRC Water Neck Flange – V1

Description

The OG billet K series water neck flange! Used as an OEM replacement but is better known for use in many of my popular fabricated products for the 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.
