Performance Aluminum Radiator (MMRAD-IS300-01) by Mishimoto®. If you demand the absolute most from your cooling system, look no further than the Mishimoto Race-Ready Performance Radiator. This race-ready radiator is perfect for your custom build. Its 32mm-thick dual-pass core ensures effective cooling, while the strutted tubes can withstand more than 100 psi and resist flexing over rough terrain or hard cornering. Designed with adaptability in mind, this radiator features 1-5/8"-12 female threaded inlets and outlets for use with our interchangeable -16AN, -20AN, 31.75mm, and 38.1mm fittings. This radiator is constructed from aircraft-quality TIG-welded aluminium, and like all Mishimoto radiators, comes backed by our signature Mishimoto Lifetime Warranty.
