    Radiator Caps

    Maintain optimal coolant pressure and improve the cooling system efficiency of your Toyota Supra, GR86, or Subaru BRZ with a high-quality radiator cap from FTSpeed. Our radiator caps are designed to effectively seal the radiator, allowing for the proper build-up and release of pressure within the cooling system. By maintaining the correct pressure, the radiator cap helps raise the boiling point of the coolant, preventing overheating and ensuring efficient cooling performance. FTSpeed offers radiator caps from reputable manufacturers such as Mishimoto, Stant, and HKS, known for their quality and reliability. Upgrade your radiator cap with FTSpeed's selection to enhance the overall cooling system functionality and protect your engine from overheating.
