Introducing the ultimate solution to your 1JZ and 2JZ GTE cooling needs - our billet upper water outlet neck designed specifically for the JZ platform. 

We made this product so you can ditch the ugly OEM casting in favour of a billet shiny unit which features a few upgrades over OEM. 

First, this neck give you the option to run a temp sensor directly into the neck. You can choose from either an M12x1.5 ( OEM sensor ) to 1/8 NPT and more ..

Furthermore, the outlet has an integrated lip to connect to a silicone hose and is also threaded to fit ORB fittings. We offer ORB to AN fittings that seamlessly integrate with the water neck to either AN16 or AN20 hoses. 

For Last, the flange side that connects to the OEM intake now has an O-ring seal, so no more leaks like with the OEM units !

This neck is good for those who use the OEM Water Pump. It bassically keeps the reciculation pipe back to the water pump unlike our "RACE" version which is made for External Electric Pumps.

If you are using an electric water pump you will need to purchase our RACE version. Please check our RACE version listing.
