For all you guys going single turbo with our Pro Series manifold (or midframe, where it's required) and a large framed turbocharger, this flange is such a sigh of relief! This flange will save you time, hassle and headaches.

Instead of having to get the OEM Toyota lower waterneck off an N/A Supra, this flange provides the transition ease and points it down for best fitment of Manifold, turbo and IC pipe!

These include mounting bolts, o-ring and CNC Cut 6061 Billet Aluminum flange. This works with the factory original lower radiator hose, with some customers cutting about 1" off the length of the hose on the radiator connection side for a better fitment.

Please test fit the lower radiator hose to determine if you need to remove a small amount of the hose for best fitment.

With the NEW PHR water neck design, the position of the thermostat remains in the factory location, allowing the thermostat to close off the bypass hole like it is supposed to and moving flow of all the water through the radiator, maximizing cooling system efficiency!

Please note the thermostat is not included, but is an optional extra
