Description
The Mishimoto Replacement Radiator Hose Kit, part number MMHOSE-350Z-03E, is a complete cooling-system refresh built specifically for the Nissan 350Z. Rather than patching together individual hoses and clamps from multiple sources, this kit bundles everything needed into one box, backed by the signature Mishimoto Lifetime Warranty. It’s worth noting up front that this kit will not fit vehicles equipped with the VQ35HR motor, so double-check your engine before ordering.
Constructed from OEM-quality EPDM rubber, these Performance-grade hoses are engineered to resist long-term degradation, helping your cooling system stay reliable whether you’re lapping an autocross course or simply commuting to work. The kit’s Black hoses are a Specific fit rather than a universal design, meaning they’re molded to match the factory routing of the 350Z and G35 rather than requiring trimming or guesswork. Clamps are included, so there’s no need to hunt down separate hardware — Mishimoto has packaged the entire cooling repair as a true one-stop solution for owners looking to restore factory-correct coolant flow.
Vehicle Applications
This Mishimoto hose kit is built for the 2003-2006 Nissan 350Z 3.5L V6, and it also covers the 2003-2007 Infiniti G35 3.5L V6. Because it is a Specific-fit product rather than a universal one, it is engineered around these particular vehicle platforms — just remember that it is not compatible with vehicles equipped with the VQ35HR motor.
