Over the last decade, the 350Z has become one of the best values in used sports cars. The effective suspension, capable engine, and attractive silhouette produce an excellent platform for any form of motorsport from drift to autocross. But, as the modifications and uses for this chassis become more extreme, those pushing their 350Z to the absolute limit need a more efficient radiator. That's why Mishimoto has created this X-Line Performance Aluminum Radiator for the 2002-2006 Nissan 350Z. Our engineering team first focused on improving the radiator's core, specifically the tube and fin specifications. This X-line 350Z radiator's core features more densely packed fins, resulting in a massive 92-percent increase in external fin area over the stock 350Z radiator. Greater fin surface area means improved heat transfer, which translates to cooler engine temperatures. Our 36mm core also dwarfs the 16mm stock unit, providing a 117-percent increase in overall core volume. Our X-line 350Z radiator features precision TIG-welded aluminum end tanks to withstand anything the road or track can throw at it. This radiator also includes a Mishimoto magnetic drain plug to capture any metallic contaminants within your engine coolant and further protect your cooling system. As with all our Nissan 350Z products, this Mishimoto X-line Performance Aluminum Radiator for the 2003-2006 Nissan 350Z includes our signature Mishimoto Lifetime Warranty for a lifetime of cooling performance.
Aluminum radiator engineered for efficient heat dissipation and optimal engine cooling. Precision-fit design ensures easy installation, corrosion resistance, and reliable performance across varied driving conditions.
