Hybrid Racing K-Series Adjustable Thermostat Housing

Stylish & Versatile

Our 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.


 
For years, customers have asked us to create a reliable solution they could count on. Most available aftermarket solutions offer a sub-par generic thermostat that either leaks, doesn’t function correctly or operates at a temperature outside the OEM specs.Our product covers those bases and more.

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 is also available with our HYPERCOOL Low Temp thermostat which will fully open around 18*F sooner than the standard version. 

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