B58 Air Filter (2 / 3 / 4 Series)

Similar to the air filter in your home, an engine's air filter serves the purpose of filtering out dirt, dust, and other foreign substances. It's worth noting that a significant portion of the dirt present in your engine enters through a contaminated air filter. The engine's air filter plays a vital role in preventing dirt from infiltrating the combustion chamber, thus minimizing the risk of internal damage and wear. By replacing your air filter with a new one, you can enhance airflow, optimize overall engine performance, and potentially even increase horsepower. Given that many of us frequently drive under harsh conditions like prolonged idling in traffic, dusty road conditions, or heavy towing, it is crucial to regularly replace the air filter in your vehicle.

Symptoms of Air Filter Failure:

1. Clogged filter media
2. Decreased engine performance
3. Potential internal engine damage
