Now a part of BorgWarner Turbo Systems, Kuhnle, Kopp & Kausch (or 3K/ Triple K for short) was one of the industries leading manufacturers, producing advanced turbochargers for a full variety of applications.
Founded in Germany in 1899, the company was at the forefront of turbocharger design for much of the 20th century, and today’s BorgWarner products owe much to the experience and design of 3K products.
Thanks to their reliability and popularity with major vehicle manufacturers worldwide, 3K turbochargers can still be found on a range of engines, and at AET (appointed as sole UK distributor in 1976), we’re still able to provide a range of repairs, replacement turbochargers and spare parts.
