NM Eng Turbo Oil Line - Features stainless steel braided line with properly clocked banjo ends. - This oil line fixes the very common oil leak coming from the factory hard line. - A must 'while-you're-at it' upgrade every time you remove the bumper to access the turbo, replace water pump housing, or upgrading your intercooler. - Unaddressed turbo line leak can cause a huge mess, starvation to the turbo, and even fire when the oil drips onto the catalytic converter (hottest part on the entire car).NM recommends replacing the return oil tubing at the same time, OEM part #: 11658617069
