Question: what are spare parts for wow?
Answer: Spare parts are a soulbound material that can be found in Mechagon, one of the two new zones that were introduced in patch 8.2. They drop from almost any mob, and are used in Mechagon crafting. Most importantly, they're used to make S.P.A.R.E. crates, which in turn can be used to make Famine Evaluator and Snack Tables.
