  • Sale
  • Regular price $449.00


The CSF Auxiliary Radiator is much more powerful than the original equipment manufacturer (OEM) radiators. The TIG welded aluminum tanks are bigger than the original plastic tanks providing greater strength and holding more fluid. CSF Radiators have a 2-row design with a 42mm core which boosts their ability to cool effectively and handle more heat. The fins are 5mm thick which helps increase the surface area for heat exchange. This improvement makes cooling more efficient and enhances airflow. The product is made entirely of aluminum which guarantees great performance and long-lasting strength. The mounting pins and brackets are much tougher and longer-lasting than the original plastic pod mounting system. The black finish gives extra protection and adds a sleek appearance behind the grilles of your F8X. CSF's extra radiators come with built-in bolt-on rock guards to protect the coolers.
