Thermostatic 8HP Oil Pan

HPR 8HP Thermostat Billet Oil Pan Kit
Upgrade your ZF 8HP transmission cooling system with the HPR Thermostat Oil Pan Kit.
 
Detail Video [HERE]
 
This complete package combines an ultra-low-profile billet aluminum oil pan, an integrated Improved Racing thermostat and a purpose-built HPR transmission cooler adapter. By integrating the thermostat directly into the oil pan assembly, HPR eliminates the need for a separately mounted remote thermostat and simplifies external cooler-line routing.
 
The cooler connections are relocated to the front of the oil pan, providing easier access when plumbing an external transmission cooler. The result is a compact, clean and properly integrated cooling solution for high-performance street, drag, drift and road-racing applications.
 
Installation Notes
Trimming of the transmission flange is required to provide clearance for the integrated thermostat. A cutting template is included with the kit.
The thermostat housing must also be machined or modified when installing the kit on 8HP45 and 8HP50 transmissions. Follow the applicable HPR modification instructions [HERE] before installation.

Integrated Thermostat System
The kit includes a high-quality Improved Racing thermostat designed to regulate transmission fluid temperature before directing oil through the external cooler.
 
The thermostat begins opening at a lower temperature than many factory transmission thermostats, helping provide better control of transmission temperatures during demanding use.
 
Thermostat Specifications
Activation temperature: 71°C / 160°F
Typical stabilized temperature: 74°C / 165°F
Full-flow temperature: 83°C / 181°F
Improved Racing lifetime warranty
