VW catalytic converter. Catalytic converters clean the exhaust gasses using heat and a chemical reaction. If the engine stays in tune, they function worry free for a very long time. If you have kept driving a poor running car, just to make it a "few more miles" the converter can plug up and damage other parts. If it rusts through or becomes blocked, it's time to replace it. This is an original equipment quality converter with the oxygen sensor located behind the converter. **EPA Federal Compliant - Not Legal for sale or use in California.
