New By-Pass Weld OEM Nissan Heater Core Water Pipes for all Non-Turbo '90+ 300ZX models. These pipes pre-modified for Non-Turbo 300ZX owners who wish to do a clean deletion of the water pipes under the plenum by welding them inhouse. This makes for a quick and simple deletion and ensures your car gets back on the road faster!

These new OEM By-Pass Welded pipes replace the often pitted and rusted water pipes that feed coolant to the heater core. These pipes are located on the rear of the motor and often over looked when doing a fresh engine build.

Why install rusty parts on a brand new engine build? These heater core pipes will ensure a clean, rust free cooling system for many years.

Sold individually.
