Oil feed lines and returns lines are an essential part of any turbo system. Oil feed lines bring oil to the turbocharger, at the same time the oil cools and lubricates the moving parts. The Oil Drain Lines take the oil that has passed through the turbo and guides it back into the engines oil pan. Without these two components, the turbochargers internals would overheat or seize causing major complications. Oil feed and Oil Return lines feature stainless steel braiding to resist heat, pressure, and expansion of the lines. Each kit comes with anodized ends or fittings for a clean show quality professional look.
