RallySport Direct carries a huge selection of radiators to improve and maximize the cooling efficiency of your vehicle. We carry excellent brands from the likes of Koyo, Mishimoto, and CSF. These radiators range from thicker all-aluminum units to factory style direct replacements. Why replace your radiator? Your factory radiator comes with plastic end tanks that can start to crack after years of pressure or stress, which can cause your engine to overheat and keep you stranded on the side of the road. RallySport Direct understands that radiators are an imperative component to the overall welfare of your engine, and now you have a great selection to choose from. Do you occasionally track your Subaru STI? Or do you live in an area like Phoenix where Mother Nature likes to troll cars and set them ablaze on a regular occasion? You can fight this with a Mishimoto Performance Aluminum Radiator. Or are you prepping for your next track day in your Subaru WRX? Choose from the Mishimoto Performance X-Line Aluminum Radiator, or the Koyo Racing Aluminum Radiator. You can also choose from a great line of CSF Racing Aluminum Radiators to keep your engine cool. And for those with a front mount turbo setup on the Mitsubishi Evolution, try the Koyo Half Size Aluminum Racing Radiator. These radiators are available for both the automatic and manual transmission, and some radiators will come with built-in oil and transmission coolers as well. While you're shopping for radiators, make sure you check out our great selection of fluid coolers, and make sure that your thermostats are in good working order. And make sure you have new couplers and hoses whenever installing a new radiator.
