After making filters for over 36 years, we make just about every shape and size you can dream up for your engine. S&B's custom filters offer a significant improvement in airflow while still stopping the dirt.
In the early years, S&B specialized in building custom universal filters for race teams and engine builders. S&B uses an 8-ply filter for these applications to help protect the engine, while still providing the performance racers demand. S&B has one of the most extensive offerings of universal filters with over 4,000 part numbers.
With the introduction of the Power Stack (inverted) design years ago, S&B revolutionized the filter industry. First, the Power Stack filter utilizes a unique inverted design to maximize airflow and filtration by substantially increasing the surface area of the filter. Second, the base of the filter incorporates S&B's Advanced Air Flow (AAF) radius design for smoother, uninterrupted airflow. The inverted top and smooth flowing base design provides better airflow & filtration than filters of similar size. The Power Stack is available in chrome, black, blue, and red.
