S&B Cold Air Intake Kits Cars
In this era of high-cfm gas engines and air-hungry diesels, S&B test their filters to Standard ISO 5011, which has produced exact and repeatable results. Due to the controlled test setting, performance certificates now accompany S&B filters for added assurance. Each certificate displays Restriction (flow), Efficiency (filtration), and Capacity (performance deterioration) results. S&B filters are also submitted for CARB approval; most are approved while those with the newest engineering innovations await approval. Made in U.S.A.
