'''{{PAGENAME}}''' is an [[Engineers|engineer]] modification that can be applied to [[thrusters]]. It reduces thermal load and increases speed, at the cost of increased power draw, and reduced integrity.

It is available in 5 grades, with the highest grade offering up to <nowiki>60%</nowiki> reduction in thermal load, and 28% increase in speed.

Although Clean drives have a reduced thermal load, they do not run significantly cooler than unengineered thrusters. This is because their increased power draw will increase the heat produced by the ship's [[Power Plant|power plant]]. The reduced thermal load of clean drives is more noticeable when compared against [[Dirty Thrusters|dirty drives]]. When rigged for [[Silent Running|silent running]], a ship equipped with clean drive tuning will take longer to overheat than if it is equipped with dirty drive tuning.
