Good upgrade for High performance engines, where the ISR Performance units opens at 60 deg celsius compared to factory 76. 5 deg celsius. Cool down your motor before heat build up! Once the engine is fully warmed up the ISR Performance thermostat will open up at a lower temperature than standard thermostats, also allowing the coolant to flow through the engine sooner
