For more than 30 years S&B filters has been making high performance air filters and breathers for vehicles and other custom applications. From its humble beginnings in a garage in Ontario, CA, S&B has continually strived to design and manufacture the highest quality and most durable re-chargeable air filter in the industry.

Today, in an era of high CFM (cubic feet per minute) performance engines and air hungry diesel engines, S&B is taking the technology of filtration and restriction to all new levels. S&B filters are now tested to the international ISO 5011 standard. This standardized testing procedure produced exact and repeatable results. Because of this environmentally controlled laboratory, consumers will now receive performance certificates with their S&B filters. These certificates will precisely and accurately display test results on Restriction (flow), Efficiency (filtration) and Capacity (performance deterioration). Consumers now have the comfort of knowing when they use an S&B filter, whether it's a replacement filter or an entire Cold Air Intake Kit, their engine is protected while receiving the increased engine performance they need.
