Ichiban Engineering - 4G63 EVO 6 - 9 - Billet Upper Water Neck

* Version 2 had landed ! *

Introducing our latest innovation - the billet upper water neck for the Evo platform, created based on popular demand from the community. The water neck has been designed using a 3D scanned Evo 4G63 head and fits seamlessly, delivering optimal performance.

Crafted from 6061 aluminum with T6 heat treatment, this water neck is built to last and withstand even the most extreme conditions. The M12x1.5 water temp sensor port on top allows for easy installation and accurate temperature readings.

We offer two different options to cater to your individual needs. The standard neck option connects to a rubber hose, just like the OEM + an internal ORB16 Thread. Alternatively, you can use the main body to connect directly to a AN16 Fitting.

Please note that the water temp sensor is not included, but can be added as an optional extra from the menu above.

Upgrade your Evo platform with our billet upper water neck and experience the ultimate in strength, durability, and performance. Choose the option that suits you best and enjoy the peace of mind that comes with knowing your vehicle is equipped with the best possible components.
