ISR Performance Water Neck Outlet - Nissan SR20DET S14 w/Integrated 1/8 npt port

The ISR Performance water neck outlet for the Nissan SR20DET S14 is an S14/S15 style water outlet with a built-in 1/8 NPT coolant temperature sensor port. It replaces the factory water neck and gives you a dedicated spot for an aftermarket temp sensor, with no separate inline adapter required.

Why this water neck

• Integrated 1/8 NPT coolant temp sensor port, which eliminates the need for an aftermarket coolant sensor adapter
• S14/S15 style outlet, matching the layout originally found on the S14/S15 SR20DET RWD engine
• Lets an S13 SR owner switch to S14 water lines for a cleaner, simpler routing

Fitment

Nissan SR20DET, S14 and S15 style. It will also fit the S13 SR20DET by adding an additional bung for another water line source and water temp sensor port. On an S13, that means no more routing water lines behind the engine: replace the current water neck with this one and use S14 water lines for a much easier install.

Installation notes

Drain the coolant before removing the existing outlet, use a new gasket on the housing, and seal the sensor threads before installing your temperature sensor. S13 owners should plan on sourcing S14 water lines and the extra bung before starting. Once fitted, refill the system and bleed carefully, since the outlet sits high in the cooling circuit.
