Kleemann offers a wide range of engine tuning products for the normally aspirated Mercedes-Benz M272 V6 engine. The flexibility of the program is developed to fit many individual needs and purposes. Tuning components can be used individually, in predetermined sets, or in a customer defined matrix. The available tuning components address all aspects of the engine and represent a “Stage” tuning concept ranging from K1 to K3.

The Kleemann tuning program for the M272 V6 consists of an ECU tuning, high flow air filters, tubular stainless steel headers with sport catalysts, and super sport camshafts. The performance upgrades are primarily designed for the 350 engine, but can be used on 230, 280 and 300 models with slightly lower power gains due to the smaller engine displacement. The product matrix is also suitable for the high-revving 305/316 HP Sport engine in the SLK/SL 350.
