Diesel engines consume air at a much higher rate than most gas vehicles. The speed of air flow is referred to in cubic feet per minute (CFM). The higher the CFM, the more difficult it is to stop the contaminants from reaching the vehicles engine. S&B designed a filter specifically targeting the diesel marketplace using 8-layers of cotton, a proprietary oil formula and 30 years of experience making filters. The result is a Performance Air Filter that greatly improves the air flow while still protecting your engine. S&B's minimum requirement for efficiency on diesel filters is 99.1%. As an example, S&B's Performance Filter for the Chevrolet Duramax Diesel 6.6L LB7 & LLY improved the air flow over the stock paper filter by 27.6% while stopping 99.44% of the dirt. S&B filters provide the performance and protection diesel consumers demand.

Want more power and better fuel economy?
It all starts with airflow. The more air that your engine breathes, the more oxygen it receives. More oxygen results in a better combustion. Better combustion translates into more power and better fuel economy. This is why your vehicle runs better on cool mornings than on hot afternoons as cool air is denser and contains more oxygen. You can feed your engine more oxygen by reducing the restriction of the airflow.
