TracTuff K24Z Billet Water Neck


I am excited to present what is sure to be the premier upper water neck solution for all K24Z swaps! 

After fielding several dozen tech questions related to initial burping of the cooling system and/ or overheating problems associated with coolant hose routing through the exhaust side of the engine bay, I decided to sit down, dissect the problem, and put a design together that would not only fix the issue... but be as universal as possible. In order to eliminate the large air pocket that was being created as a result of exiting the exhaust side, I needed to rotate the water neck. The flange adapter does the job of directing water as well as converting the bolt pattern so that the water neck can sit perfectly level, regardless if you want the upper hose to exit the intake or exhaust side! 

The design incorporates two -16 ORB ports so you can select the outlet orientation and the type of connection. An ECT sensor port is included but it has been moved from the OEM location. The hardware kit includes four M8 stainless steel socket head bolts, a -16 ORB plug, your choice of 1.25" hose barb or -16 male flare port fitting, and two OEM o-rings. You only need of 1.99"" of space between the firewall and the water necks mounting surface to run this!

Want me to weld up a filler neck, fill pot, or swirl pot using this flange? Send an email to sales@tractuff.com so I can get you scheduled. I will not have pictures of said items until someone has commissioned me to make something and I have had a chance to photograph it.

NOTE: If you would like to retain heat you will need to convert one of the -16 ORB ports to a smaller/ more common thread size to slip hose fitting.

        EXAMPLE: -16ORB (1-5/16"-12) male o-ring boss to -8 ORB (3/4"-16) female o-ring boss + -8 ORB (3/4"-16) male o-ring boss to your            preferred hose size or the closest available size on the market.
