S&B Filters S&B Filters specializes in air intake systems for your diesel truck. They are located in California where they have a 60,000 sq. ft. facility. They use all American made products in their design and manufacturing process. They use laser scanning for precision and CNC maching to ensure quality and great fit. They create rapid prototypes and keep new products coming to you. All applicable S&B products are emissions-tested and certified in 50 states and are backed by the S&B warranty policy.
S&B products are ISO Certified. 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 S&B 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.
The end result is simple: increase 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.
