One of the easiest ways to increase engine horsepower and torque is by bolting on a cold air intake system. S&B Filters produces cold air intake systems for both gas and diesel engines, which improves airflow to your engine by over 40 percent and leads to better mileage, improved throttle response, and, of course, more power. These cold air intakes are available with either reusable cotton filters or replaceable dry filters.
Other S&B products include air filter cleaning kits and vent filter breathers. Manufactured by S&B Filters.
