Power Lens

Power Lens is an item introduced in Generation IV that adds 8 Special Attack EV points to the Pokémon holding it when it gains Experience Points, regardless of the EV point(s) it normally gains from the opposing Pokémon. While it is held, it reduces the Pokémon's Speed stat by half. 
Prior to Generation VII, it rewarded 4 Special Attack EV points whenever the holder gained Experience Points.
