Stock replacement hydraulic valve lifter for the M52, M54 and S50 S52 engines. These lifter buckets can last 150,000+ miles but then they no longer fit on the valve stem correctly and a ticking or knocking noise can result. If the lifter is no longer seated correctly, it can lead to the valve not opening correctly. Replacement is straight-forward but requires special tools for working with the camshafts. This item fits the following BMWs:
1995-1998 E36 BMW 323is 323ic 328i 328is 328ic M3
