Valve Guide-528e (82-88), 325e (84-87), 325i (87-91), 525i (89-90) (Canyon V11523-9 or V11523) - engine valve guide that cross-references directly to BMW OEM part number 11121280523. It was considered the 1st Oversize (13.05 mm × 7.00 mm) for the M20 inline-six cylinder. However, BMW stopped offering the 13.00 mm standard guide as a service replacement part, designating the 1st oversize guide (11121280523, 13.05 mm OD) as the baseline replacement for M20 cylinder head rebuilds. Unless you're going up to the largest (2nd oversize, 13.25x7.00mm) guide, this is the smallest you can now buy.
These are only for sale in multiples of 6pc.
