Basic Boost Solenoid Kit - BMW E90 E70 M57 3.0L

The factory boost solenoids, also known as pressure converters, are a common issue on the M57 engine. The vacuum hose also hardens over time due to heat, and can crack or split, leading to vacuum leaks. These failures result in a loss of power, limp mode, lazy throttle response, and check engine lights. This basic kit includes two replacement boost solenoids to restore engine power and performance, plus new silicon vacuum hose that will last much longer than the OE rubber vacuum hose.
