This is the in-tank fuel pump for the E46 M3. The fuel pump in your vehicle is essential for delivering the proper amount of fuel at the correct pressure. Usually, they fail unexpectedly and at the worst possible time. Replace yours to prevent being stranded with a broken fuel pump. This fuel pump installs easily in the place of your broken or worn pump. All wiring connections are the same to make this an easy plug and play installation. Don't take a chance on an inferior fuel pump from the local auto store that may leave you stranded again. Choose a quality unit to ensure thousands of worry free miles. Includes seal.

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. Level 1 kit includes the following; Oil separator Hose from oil separator to dipstick tube Hose from oil separator to valve cover Hose from intake manifold back to the connector hose Hose from oil separator up to the intake manifold

The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.

This is a NEW alternator from the OEM manufacturer, Valeo. No core charge applies.
