Mishimoto has developed a carbon fiber radiator cap to enhance the style of your engine bay while maintaining the pressure in your cooling system. Getting the most out of your performance parts comes down to the details. When faced with hard driving conditions, a vehicle’s cooling system becomes highly pressurized. OEM caps are not equipped to handle higher pressure, causing fluid to leak out into the overflow reservoir.

The Mishimoto radiator cap is rated at a higher pressure and will keep coolant where it needs to be-flowing within the system. The sleek carbon fiber exterior will add an unexpected touch of style. Constructed from hand laid carbon fiber. Rated at 1.3 Bar (19 lbs pressure). Fits most import vehicles.

The Mishimoto performance aluminium radiator for the Mazda RX-8 is the ideal upgrade to the stock RX8 radiator. Designed and specifically engineered to maximize cooling efficiency by up to 30%, boost engine functions and protect your car from overheating. Whether you use your Mazda RX-8 for daily driving or take it to the track, many people overlook the importance of installing an upgraded radiator in their engine. A stock radiator can not handle the heat that comes along with having a great deal of horsepower. The Mishimoto Mazda RX-8 radiator features a lightweight dual core, 100% brazed aluminum, and polished end tanks. Every Mishimoto Performance Radiator is a direct OEM fit, making installation effortless, no cutting or modification is required.
