SUPERTECH FORGED PISTONS Supertech Performance forged pistons use modern Formula-1 design elements to create the finest piston available for your engine. Designed to be the lightest, strongest pistons available for this application, these pistons feature X Box technology, creating a more rigid forging with a stronger dome in a more compact design. In addition to their ultra-light weight, these pistons are made with skirts designed to radically reduce drag and ring land designed to enhance ring seal, increase power, and reduce detonation.
