ISR Performance Water Neck Outlet - SR20DET S14 w/ Integrated 1/8 NPT Port
ISR Water Neck Outlet - Nissan SR20DET S14/S15 Style With Integrated 1/8 npt Coolant Temp Sensor Port
This Similar part was originally found on the S14/S15 SR20DET RWD engine, this water outlet will also fit the S13 SR by adding an additional bung for another water line source and water temp sensor port.
No more Need to route water lines behind the engine on your S13. Replace your current water neck with this one and use S14 water lines. Much easier install.
No more need for aftermarket coolant sensor adapters because of the integrated 1/8 npt Coolant Temp Sensor Port
