LUK is an OEM Flywheel manufacturer for BMW.  


LuK dual-mass flywheels absorb engine vibrations before they are transmitted to the driveline where they can create gear rattle.

These units feature a built-in damper designed to isolate engine torque spikes and prevent transmission damage. By design, dual-mass flywheels cannot be resurfaced.

This all makes the LuK dual mass flywheel the ideal solution.
With one drawback: the higher the mass reactance of the vibrating masses, the more excessive the resonance increase and associated torque peaks. With the dual mass flywheel, this would be easily perceived when starting and stopping the engine; much more easily than with a conventional clutch system. Additionally: the smaller flymass of the engine has less of a stabilizing effect on the speed fluctuation of the engine.

Thanks to decades of experience in clutch building, the LuK specialists were able to find an excellent solution to this problem. An additional damping device effectively prevents resonance overload. In normal operation, however, this additional damping device has no function and the torsional vibrations of the engine are filtered out by spring dampers.

Friction and spring rate - the correct ratio is important.
For optimal vibration isolation and soft resonance passage when starting and stopping the engine, the ratio between friction and spring rate must be optimal. The length of the springs is a key factor: The softer a spring, the more efficiently vibrations are isolated. The extra-long springs of the latest generation of dual mass flywheels significantly reduce the spring rate compared to a first generation dual mass flywheel. In routine driving operations, excessive resonance increases are kept almost completely away from the gearbox.

Features and Benefits:

  • Top driving comfort
  • Absorbs vibrations
  • Prevents noise
  • Enables comfortable, low-revs driving
  • Saves fuel
  • Relieves crankshaft and gearbox

Great value
Installation is quick and easy, as it fits perfectly in the existing air filter housing without any modifications needed. The rigid panel design ensures a tight seal, preventing any unfiltered air from entering the engine. In terms of performance, this air filter does a commendable job of filtering out dirt, debris, and other particles, aiding in better engine performance and fuel efficiency. It improves the overall air intake, allowing the engine to breathe easier and perform optimally.
