K-Tuned updated the design of our popular K Series Swivel Neck Thermostat Housing to use an OEM style thermostat which will maintain the factory cooling recirculation port. The OEM styles T-Stat will close off the recirculation port when the thermostat opens. We also have included two rad fittings, the standard 1.25" hose outlet and an optional 16AN hose outlet. Swapping out to different temp thermostats would use a 2002 RSX Type S Thermostat.

The design replaces the top half of the original thermostat housing and requires you to keep the back half of the black plastic housing. It uses a threaded -16 rad hose port that allows you to easily convert between 1.25" and 16AN radiator hoses. Our swivel neck allows 360 rotation to position your rad hose perfectly. Includes -8AN accessory port with optional plug.
