S&B uses 8-layers of cotton to produce air filters and intake kits with substantially more airflow and radically high efficiency rates (over 99.0%) giving the consumer more power without the fear of engine damage. S&B backs up this claim by publishing ISO 5011 Test Results on its filters and intake kits.

S&B won't release a Dry Filter until our testing demonstrates that the dry filter technology can out perform 8-layers of cotton gauze in airflow while still maintaining an efficiency rate of at least 99.0%. Our competitors currently selling Dry Filters do not share this same philosophy. 

The filters are the new S&B power stack with "Absolute Air Flow" built-in velocity port. They are available in Black, Chrome, Red or Blue. The inlet is 3 1/2" with a 7" long cone filter.
