ALL S&B FILTERS ARE WASHABLE AND REUSABLE!

CARB approved. Each filter S&B produces is manufactured to the highest standards and submitted for CARB approval. In some cases, because of engineering innovations that are brand-new, approval is still pending.

S&B Filters tests and posts their findings to the standards most other companies are scared to use: ISO 5011

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 S&B to establish the air filter performance benchmark, which they 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 industrial applications.

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 they seek innovations and improvements in their product line, and to test their products so they meet the highest standard possible. They 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!
