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

Our two-layer silicone radiator hose kit for the early 350Z (2003-2006), blue finish. A direct replacement for the factory rubber upper and lower hoses, with the temperature and pressure tolerance silicone offers over aging OEM rubber.

What It Does

Replaces the factory rubber radiator hoses with two-layer silicone construction. Silicone holds up to higher sustained coolant temperatures and pressures than rubber, and it resists the expansion and gradual breakdown that turns 20-year-old factory hoses into ticking time bombs. The blue finish keeps the engine bay looking dressed up for the classic blue-on-Z aesthetic.

Fitment

Fits the 2003 to 2006 Nissan 350Z (early Z33). Direct replacement for the factory upper and lower radiator hoses.
