Tested to a higher standard.
S&B tests to the internationally accepted ISO 5011 Standard when testing for airflow, efficiency and capacity. This is the same protocol used by most of the large automakers.
Airflow testing shows us how we compare to stock and our competitors. The goal is to beat both.
We test for efficiency to make sure that your engine is protected from debris while sucking in even more air. Lastly, we monitor the capacity of the filter to see how much dirt it can hold before needing to be serviced.
