Show original supplier description

The K-Tuned Swivel Neck Thermostat is engineered as an upgraded housing for all K series engines, featuring a redesigned unit that utilizes an OEM-style thermostat. This design maintains the factory cooling recirculation port, ensuring proper operation as the T-Stat closes off the port when the thermostat opens. The housing comes equipped with two radiator hose fittings: a standard 1.25" outlet and an optional 16AN outlet, providing flexibility for various cooling system setups. Key features of this thermostat housing include its ability to allow 360 degrees of rotation, facilitating easier hose routing and installation. It also incorporates a -8AN accessory port, which comes with an optional plug for added versatility. For those looking to fine-tune their engine's operating temperature, different temperature thermostats can be swapped in by using a 2002 RSX Type S Thermostat. Installation involves replacing the top half of the original thermostat housing, while retaining the back half of the black plastic component. The product includes the necessary hose end and 16AN outlet fittings to complete the installation.
