Professional Installation Advice

When installing a new A2740904180, it is mandatory to replace the oil feed and return lines. Carbon buildup in the old lines can restrict oil flow, leading to immediate bearing failure in the new turbo. Additionally, ensure the engine oil and filter are changed to prevent contaminated oil from entering the precision bearings.
