Conclusion

There are many different types of air filters for diesel engines, but they all have one common goal: to keep the engine clean. The most common type of air filter is the paper filter, which is designed to trap dirt and debris before it can enter the engine.

These filters need to be replaced regularly to maintain optimal engine performance. Other types of air filters include oil-based filters and foam filters. These filters can be used in conjunction with paper filters to provide even better engine protection.
