Engine Protection
The oil filter is essential in protecting the engine by preventing harmful particles from causing damage. This ensures that the engine runs efficiently and reduces the risk of breakdowns.

A clean oil filter contributes to better engine performance. It allows the engine oil to flowly, reducing friction and improving the overall functionality of the engine.
Longevity of the Vehicle
Regularly changing the oil filter can significantly extend the life of your Audi A4. By keeping the engine clean and well-lubricated, you reduce the wear and tear that can lead to costly repairs.
Types of Oil Filters
