The PROMINI stress bar is a great addition to your Cooper S. The bar is manufactured from light weight, aircraft polished aluminum, or powder-coated steel. Both bars offer maximum stiffness derived from the direct tower-to-tower design. The E.P.L. (Eccentric Pre-Loader) allows you to slightly pre-load the bar after installation. Requires the installation of our high performance air intake kit(part number 155527) to provide the required clearance over the factory air filter housing.
