Radiator Fan Control Module

By reducing heat transfer, this upgrade helps to minimize power loss that can occur in warmer climates, ensuring more consistent engine performance. Specifically designed for the Nissan 350Z, Infiniti G35, and M35 vehicles manufactured between 2003 and 2010, this kit offers a direct-fit solution. The primary function of the Iso Thermal Upgrade is to act as a thermal barrier, preventing excessive heat from the engine bay from negatively impacting the intake air charge temperature. While the product page emphasizes return policies and customer service regarding fitment, it does not specify any special installation requirements beyond confirming compatibility for the 2003-2010 Nissan 350Z, Infiniti G35, and M35 models. It is advisable to ensure that the product is appropriate for your specific vehicle configuration before purchase.
