Original BMW Oil Pump Chain Guide Rail Assembly for BMW 1, 3, 5, 6, and 7 Series, X1, X3, X5, X6, and Z4 (2006–2016)

Covering BMW's N51, N52, N53, N54, and N55 six-cylinder engines, the Original BMW oil pump chain guide rail assembly guides the chain that drives the oil pump on 2006–2016 BMW 1, 3, 5, 6, and 7 Series, X1, X3, X5, X6, and Z4 models. The oil pump, its drive chain, and the suction pipe together keep a constant supply of oil moving through the engine, so the chain needs to stay on a controlled path. This assembly comes with its guide rails and tensioner, and it weighs 220 g. It is made in Switzerland.
