The Z1 Lower Radiator Hardpipe with formed Silicone Elbows fits all 1990+ Nissan 300ZX's with stock and aftermarket radiators.

The hardpipe section eliminates the issues with sagging and collapsing often associated with the stock rubber lower hose.

What sets the Z1 Lower Radiator hardpipe kit away from the competition are the high quality perfectly formed Silicone Elbows. Other hardpipe kits include standard rubber elbows, which with time will degrade and eventually split or bust. The high quality silicone elbows provided in our kit will not deteriorate over time. This kit is designed to outlast the life of your car and then some.

Available in several finishes, with your choice of BLACK, BLUE, or RED couplers complete with clamps. You may also select our Z1 Silicone Upper Radiator Hose and / or Z1 Silicone Radiator Overflow Hose as an option below for a discounted price to really finish the front of your engine bay. Please choose the appropriate options below.
