Description
Nissan 350Z Z33 VQ35DE (03-06) Mishimoto X-Line aluminium radiator
The Mishimoto X-Line radiator 350Z is the heaviest-duty radiator Mishimoto makes for the 2003-2006 Nissan 350Z (Z33) with the VQ35DE. The 350Z is a popular platform for drifting and autocross, and anyone pushing it to the limit needs more cooling capacity than the stock radiator offers.
The X-Line core is 36 mm thick and, according to Mishimoto, has 117 percent more core volume and 92 percent more external fin area than the factory radiator. It holds 75 percent more coolant, keeping temperatures more stable during long sessions. The radiator is full aluminium and TIG-welded, and comes with a 1.3 bar radiator cap and a magnetic drain plug with dowty seal.

Installation and delivery
The X-Line radiator mounts in the original location and uses the existing brackets and hoses. Mishimoto rates the installation as medium. Fill and bleed the system carefully after installation; the larger capacity means more coolant is needed than with the stock radiator. The Mishimoto radiator installation guide is available below. Lead time: 4 to 7 days.
More core, more fins, more coolant: the X-Line is built for 350Zs that are pushed to the limit.
Why choose this Mishimoto X-Line radiator 350Z?
For a stock 350Z the regular performance radiator is enough, but if you drive your Z hard on track or in the drift, the X-Line gets the most out of the available space. More volume and more fins mean more margin for hot days and long sessions, backed by the Mishimoto lifetime warranty.
