Mahle Performance piston rings evolved from their pioneering use of piston ring simulation and computer development tools to develop rings that provide "free" horsepower by successfully minimizing friction. A large selection of coordinated piston ring sets is available in a variety of sizes, designs, materials, and coatings designed to exceed your high performance requirements. The difference is evident on the dyno and on the track.
