Description

This two-piece oil line set connects the front oil cooler to the thermostat and includes both the supply and return lines. The long lines run laterally under the vehicle and are an essential part of the Porsche 964's external oil circuit.

They transport the engine oil under pressure to the radiator and back to the thermostat, ensuring stable temperature control and reliable lubrication. As they age, the lines can corrode, leak, or become clogged internally – leading to poor cooling performance or increased oil temperatures.

Replacing the complete set restores full, pressure-stable oil flow and ensures optimal operating conditions, especially in high-performance or thermally stressed engines such as those in the 964 and 964 Turbo.
