This is a custom hand-made water neck, which eliminates the thermostat.
This is for 6-bolt 1g-style setups. Will not work with 7-bolt water pipe, but you can convert to 6bolt water pipe with this.
Radiator cap not included. This neck uses a large (domestic size) radiator cap. These caps fit:
- Meziere SafeCap WCC301: 16 psi, billet aluminum, black anodized, locking
- Meziere SafeCap WCC307: 25 psi, billet aluminum, black anodized, locking
- Mishimoto MMRC-13L: 1.3 bar (19 psi)
These are hand-made to order, and usually take about 2-4 weeks to ship.
