Bavarian Autosport served the needs of BMW and MINI enthusiasts from 1974-2019. In 2019, ECS Tuning acquired the Bavarian Autosport brand, committing to continuing the tradition of excellence Bav Auto is known for. Over the years, Bav developed their own brand of parts, accessories and upgrades. A lot of these parts are engineered and built by OEMs (Original Equipment Manufacturers – companies who make original parts for BMW, MINI, and other European marques). Just as BMW and MINI do, we work with a variety of manufacturers in Europe, Asia and North America. In many cases, we have sourced parts that are superior to Original Equipment.
A lot of time and resources have been put into developing and evaluating these products, as well as the companies who produce them. We stand behind every product we sell. If any product fails to meet our standards — or our customers' expectations — we won't sell it, and we're certainly not going to put the Bavarian Autosport name on it. In fact, we're so confident in the quality of these parts that we back every Bavarian Autosport brand part with a 2-year warranty.
