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.

S&B attached approximately 80,000 packets of ISO Test Dust to an ad we ran in October's issue of Diesel Power magazine which was sent to the magazine's subscriber base. Click on the attached PDF file to see the ad S&B ran.
