TracTuff PRB/PRC Water Neck Flange – Race

Description

The RACE water neck flange is a slimmed-down version of the original. Some intake manifold designs lead to fitment issues, and this variant solves those problems. Awesome option for those that use the K20A, K20A2, K20A3, K20Z1, and K24A1 cylinder heads.

The flange is beautifully machined from 6061-T6 and incorporates an OEM o-ring groove and a -16 ORB thread. The raised lip that serves as an o-ring seat for -16 ORB thread also doubles as a generous socket that can be used to weld custom projects.

The hardware kit includes two M6 socket head bolts and a Genuine Honda gasket. This flange variant does not have a water bypass hose port, making this a DRAG RACE ONLY product where a thermostat is not likely to be used.
