Rein Coolant Temperature Sensor - BMW E6X, E7X, E9X

Product Details

The Rein ELC0090 is a critical maintenance component for BMW N52-series engines, replacing the often-ignored "angle connector" located beneath the intake manifold. Over years of heat cycling, the plastic housing of the original connector becomes extremely brittle and is prone to cracking during other engine services, such as starter replacement or DISA valve repair. Replacing a failing heater connector with the Rein ELC0090 restores proper crankcase pressure regulation and ensures your engine remains free of vacuum leaks. Manufactured by CRP Automotive to strict European standards, this part provides the exact fit, form, and function of the original BMW dealer part at a fraction of the cost, making it the ideal choice for a high-mileage cooling or breather system overhaul.
