ISO 5011 Certified
Testing to the Highest Standard
The ISO (International Organization for Standardization) establishes and specifies uniform test
procedures, conditions, equipment and a performance report to permit direct laboratory performance
comparison of air filters and induction systems.
Testing to these high standards enables us to accurately measure our products against not only OEM
[Original Equipment Manufacturer] equipment, but also to the competition, allowing us to establish
the air filter performance benchmark, which we are determined to do.
ISO is a worldwide federation
of national standards bodies. The work of preparing International Standards is normally carried out
through ISO technical committees. The specific individual International Standard utilized by S&B
and automotive manufacturers establishes and specifies uniform test procedures, conditions, equipment,
and a performance report to permit the direct laboratory performance comparison of air cleaners,
in this case, those used on internal combustion engines and compressors used in automotive and
The performance characteristics of greatest interest are airflow restriction (differential pressure),
dust collection efficiency and dust capacity. The ISO 5011 Standard is what S&B Filters adheres
to as we seek innovations and improvements in our product line, and to test our products so they
meet the highest standard possible. We feel this is the standard that all performance filter
manufacturers should be using to develop their products.
The end result is simple: increased horsepower by reducing the restriction of the air
filter and/or intake kit while still protecting the engine. Trust your performance needs
to the only performance filter manufacturer who tests to these standards and post results
- trust S&B.
