Your oil is the most important component of your engine, and keeping your oil clean should be your number 1 priority. Genuine Volkswagen Oil Filters are specifically designed to provide exceptional filtration of your oil, at a reasonable cost, ensuring that the oil provides sufficient lubrication for your engine's internal components. Genuine Volkswagen Oil Filters contain significantly more filtering medium than aftermarket filters (sometimes twice as much), ensuring proper flow of oil through the filter element, while trapping damaging particles. Proper filtration is crucial in preventing excessive wear and damage to your engine, keeping it in top running condition for years to come. Can Style filters also feature bypass and anti-drain back valves ensuring sufficient oil supply to the engine's internal components during cold starts and heavy acceleration.
