    Radiator Caps

    If you are experiencing any sort of overheating, and know that your cooling components are working as they should be, then it can be something as small as a radiator cap. Radiator caps in a sense, work like thermostats, and allow the coolant to reach a certain boiling point for improved cooling efficiency. But either way if you live in a hot climate, or only save your ride for summer fun, a radiator cap is a cost effective option in supplementing your cooling system. 

    Choose from a great selection of radiator caps from the likes of COBB, Prova, Mishimoto, HKS, Koyo, and Greddy among other great brands. You can also choose from 1.1 bar to 1.3 bar radiator caps depending on your vehicle's tolerance levels. And while you're at it, make sure you replace your thermostat, and we also carry a large selection of all aluminum radiators to improve the cooling efficiency of your vehicle.
