This is a wastegate turbine repair kit for BMW N20 turbocharged engines, made from steel to replace the worn wastegate damper mechanism that controls boost pressure. According to the manufacturer the repair can be installed on this engine without removing the turbine from the car, though it requires argon welding to fit; the kit addresses common overpressure-relief wear that causes boost fluctuations and rattling.

Fitment: BMW 2, 3, 4 and 5 Series, X1 and X3, with the N20B20 engine, covering the F22, F30, F32, F10, E84 and F25 chassis.
