Hybrid Racing's thermostat housing was designed for customers looking for OEM quality parts that function beyond the constraints of factory parameters. The sculpted housing is machined from billet aluminum and then treated to a high-quality black anodized finish. This thermostat housing is adjustable, allowing it to fit many engine and radiator combinations.

The main housing has a -16 ORB thread which offers flexibility (can rotate 360*) between an OEM style radiator hose or the option to run AN fitting for your radiator. We include a single-threaded port (M18x1.5) in the top section that can be used to add an additional sensor. With an OEM K-Series thermostat (opens at 172.4*F) installed, expect factory functionality and reliability. We also include an OEM-style O-ring to prevent any leaks.

This kit fits all K20A/Z thermostat bases & K24(A) series bases.
