Fits 5/6 speed non-M E46's & X3. ****M3/Z4 part number (21522229675) for the hardline attached to slave cylinder is different from what is included (21526774230), you may need to source another hardline to fit for use with M3 or Z4. Please message me if you have questions regarding fitment. All parts are FTE (bracket and hardline loop are OEM) and look to be recently new, but I received them with the hardline and softline separated, and master cylinder inlet unplugged. Nothing was visibly dirty, when I wiped out connections used brake fluid was present but not solid contaminants. For good measure I recommend disassembling, inspecting O-rings and flushing lines before installation.
