Original BMW Flywheel Bolt for BMW E46 3 Series, E60 5 Series, X3, X5 3.0i, and Z4 (2003–2006)

On M54 six-cylinder BMWs from the 2003 E46 330i through the 2006 X3, the Original BMW flywheel bolt 11-22-7-519-572 fastens the flywheel to the crankshaft. BMW calls this fastener an "ISA screw." Its thread is M12 x 1.5 with a 29.15 mm length, and each bolt weighs 36 g. BMW has made this version since September 2002. It is made in Germany.

Original BMW Parts carry a 24-month parts warranty.

Flywheel bolts carry every bit of the engine's torque into the flywheel and clutch, so they work under heavy load and constant reversals. A loose or poorly secured flywheel can show up as clutch slip or vibration, or as knocking and rattling from the bellhousing area. A bolt that shears can do severe engine or transmission damage. This bolt is specific to the M54 engine, which is why the fitment runs from the E46 to the E83 X3 and the E85 Z4 but stops at M54-powered cars. Confirm your car in the fitment table below before you order.
