Universal Filters
What You Want, When You Want It!
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.
