Constructed entirely of brazed aluminum with robotic TIG-welded end tanks and a brushed finish, the radiator offers both strength and style. The inclusion of a high-pressure 1.3 Bar cap raises the boiling point, while the magnetic drain plug protects against metallic contamination. It installs effortlessly into the OEM mounting locations - no trimming or modifications required. Please note this radiator is designed exclusively for manual transmission 350Z models; automatic versions will need the Mishimoto Universal Transmission Cooler Kit. Backed by Mishimoto's lifetime warranty, this radiator provides long-lasting performance and peace of mind.
