Description I chose to incorporate an S&B filter on my intake system because they are proudly designed, engineered, are manufactured locally, and they still value small businesses. S&B filters utilize a washable and reusable 8-ply cotton-gauze filter material that helps protect the engine while still providing the performance we demand. To ensure maximum efficiency of your air filter, it is recommended to clean and re-oil using an S&B Precision Cleaning & Oiling Kit at least every 12,000 miles. The specific cleaning interval will depend on your driving conditions. It is recommended that you inspect your filter every oil change or 6,000 miles. If debris has built up on your filter equal to the height of the wire mesh, your filter should be cleaned and re-oiled immediately. Servicing your filter more frequently will result in better performance. Air filter cleaning kits can be purchased directly from S&B Filters HERE. ISO 5011 Standard S&B backs up their claims by publishing ISO 5011 test results (the same standard used by most OEM’s) on their filters and intake kits. Testing is performed at the vehicle’s max-rated airflow obtained at peak horsepower to ensure engine protection even under extreme driving conditions. ISO is a worldwide federation of national standards bodies. 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. Testing to these high standards enables S&B to accurately measure their products against not only OEM (Original Equipment Manufacturer) equipment, but also against the competition, allowing S&B to establish the air filter performance benchmark, which they are determined to do. 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.
