The ECS 6PK1358 Kevlar Reinforced Belt (6PK1358ECS / ES#4759990) is a performance accessory drive belt for the supercharged MINI Cooper S engine. Its Kevlar-reinforced construction resists stretching and slipping better than a standard rubber belt, which matters on this application because the belt also drives the supercharger; it is designed for use with the factory 2% and aftermarket 16% overdrive pulley systems.

Fitment: MINI Cooper S and John Cooper Works, chassis R52 (convertible, 2005-2008) and R53 (hatchback, 2002-2006), all equipped with the supercharged W11 1.6L engine.
