To continue supporting our Tacoma customers, Mishimoto has developed an all-new performance aluminum radiator for the 2.7L/4.0L Tacoma. Our radiator features a full-aluminum design and precisely TIG-welded end tanks for a substantial improvement in durability over the stock plastic radiator. Our aluminum radiator features a 1.65”-thick two-row core with strategically designed fins for maximum cooling efficiency. Packing more fins into our core results in an 84% increase in external fin surface area over the stock radiator. This fin surface area increase directly impacts heat transfer, resulting in a 53% improvement in heat rejection. As with all our products, this second-generation Toyota Tacoma Performance Aluminum Radiator includes our signature Mishimoto Lifetime Warranty.
