Even without the extreme heat generated by forced induction, the high-revving 3.4-litre flat-six requires serious thermal management during heavy track use. Keeping oil and coolant temperatures in check is the only way to prevent the ECU from restricting power. Upgrading your cooling system with a center radiator retrofit significantly increases frontal cooling capacity. Pairing this with heavy-duty oil coolers and uprated water pumps ensures your Boxster or Cayman maintains stable fluid temperatures lap after lap.
