Equipping the Powershot Nitrous modification allows the player to activate an oxidising agent that will in increase the power output of the vehicle's engine for the duration of its usage. It can only be activated upon the vehicle's nitrous tank being completely filled. Nitrous will slowly regenerate as the player drives their vehicle but the rate of replenishment will dramatically increase if the player successfully performs dangerous driving acts or by passing through a Repair Shop. The professional Powershot Nitrous modification offers a larger tank capacity.
