Unlike traditional BMW engines, modern engines, like the B48 and B58, use a volume-flow-regulated oil pump. Instead of providing a consistent volume of oil, these new systems control oil supply at each individual operating range.

This Control Valve Solenoid is a critical component in the volume-flow-regulated oiling system. This piece seamlessly adjusts the oil pressure based on inputs from the DME. In the event of failure, this means the engine oil supply system may become restricted.

Thankfully, Bremmen Parts offers this high-quality, OE replacement Control Valve Solenoid at a fraction of Genuine price. Built with durability and fitment in mind, this component is an exact fit for your BMW.

If your engine has higher mileage, don't neglect rod bearing replacement! These bearings are sandwiched between the connecting rod and crankshaft journal and are prone to failure due to overheating, lack of lubrication, or general wear. Replace your rod bearings and prevent a spun bearing.

Starting with ACL’s high-performance bearing shells, our Race Series bearings are built to withstand extreme RPMs and stress. Utilizing a "Duraglide" tri-metal construction and a high-strength overlay plate, these bearings offer superior oiling and heat resistance for high-RPM operation.

Our WPC-treated bearings take ACL’s already impressive design and enhance it even further. The WPC treatment process strengthens and smooths the bearing surface by firing high-speed, ultra-fine particles at the bearing shells, reducing friction and improving durability. This advanced surface treatment ensures smoother operation and improved heat dissipation, which are critical for any high-performance engine.

Kit includes:

Turner Motorsport WPC-Treated Race Series Rod Bearing Shells (8) Genuine BMW Connecting Rod Bolts (8) Assembly Lube (4 oz.)
