Nitrous Oxide Systems
Increasing airflow into an engine so more fuel can be burned is a proven way to make more power, and mods like cold air intakes and performance intake manifolds allow greater airflow. But oxygen, the only part of air that supports combustion, is just 21% of the total content, so perhaps the most efficient way to make more power is to just increase the level of oxygen in the combustion chamber. And that’s what happens with a nitrous oxide system.
