Original BMW Engine-to-Transmission Dowel 14.5 mm for BMW 1-8 Series, M, X3, X4, X5, and Z4 (1978–2024)

At the joint where the engine block meets the transmission bellhousing, this Original BMW dowel, part 11-11-7-524-470, aligns and locates the two housings on a wide range of BMW cars. Locating dowels hold mating parts in exact register so the bolts only have to clamp. BMW specifies a 14.5 mm diameter and lists the dowel at about 1 gram, with production starting in February 2004. It is made in Germany and priced and sold individually.

Original BMW Parts carry a 24-month parts warranty.

BMW uses this one 14.5 mm dowel on a remarkably long list of engines, from the M20, M40, and M50 through the M52, M54, N52, N54, N55, and N20, and on to the B46, B48, and B58. BMW's parts data carries it from the E30 3 Series and E34 5 Series through the F30, F32, and G20, plus the F80 M3 and F82 M4. Order the quantity your job calls for, since each dowel is sold individually.
