The name mahle is synonymous with both Porsche and performance. From the engineering of the world s first aluminum alloy piston, to the development of the nikasil coated cylinders (nikasil is the wear-resistant cylinder coating now used throughout the industry), the mahle tradition powers not only Porsche street cars, but also today s most advanced Porsche racecars. If you want more horsepower out of a daily driver, or ultimate performance for a full-on racecar, mahle pistons and cylinders can handle it. These cylinder and piston sets feature nikasiltm coated cylinders which reduce wear and a matched aluminum piston in several different compression rations. Includes rings and wrist pins.
