ISR Performance Silicone Radiator Hose Kit Nissan 350z 2003-2006 - Black

The ISR Performance silicone radiator hose kit for the 2003 to 2006 Nissan 350Z in black replaces the old, worn factory rubber radiator hoses with two-layer silicone units. These hoses are designed to take a higher range of heat and coolant pressure than OEM-style hoses, and the black finish keeps the Z33 engine bay looking factory-clean while quietly upgrading it.

What you gain

• Two-layer silicone construction for strength well beyond the original rubber
• Rated for higher heat and coolant pressure
• Resists heat to protect cooling performance on a hard-driven VQ35DE
• Tidies up the engine bay with a clean, uniform look

Fitment

Nissan 350Z, 2003 to 2006. ISR offers this kit in black, blue and red for most applications, so pick the color that suits your bay.

Install

Drain the coolant, replace the hoses with new clamps, refill with fresh coolant and bleed the system. Early Z33 hoses are now close to two decades old, which makes this a worthwhile preventive job even if the originals have not failed yet. Recheck the clamps after a few drives.

All ISR Performance products are designed for off-road use only.
