For 2003-2005 Audi Allroad Quattro and 2003-2004 Audi A6 Quattro applications, the engine oil and oil filter must be changed to ensure proper turbocharger function. Follow the installation guide included in the box. Clean the air intake and exhaust tract before installation, and verify fresh oil supply to help prevent oil coking and premature wear. Replace the air filter if contamination is present.

Quality Assurance

This turbocharger is manufactured with 100% new components and tested for trouble-free operation. It is engineered to match O.E. performance and comply with federal regulations. Most turbocharger failures are linked to oil starvation from old or contaminated oil, so proper maintenance and clean lubrication are critical for long-term reliability.
