Hel Performance Rear Differential Oil Cooler Toyota GR Yaris 20+

We’ve developed this kit to combat the excessive heat problems that have developed with the GR’s under aggressive driving conditions. This kit features an 82 degree temperature switch paired with a Setrab oil cooler matrix to extend the lifespan of the differential and fluid while keeping it in an optimal operating temperature window. Complete with pre-assembled AN8 hoses, wiring harness with a fused relay and installation instructions.
