Octane Booster

Fuel System

Increases gasoline octane rating to prevent knock and detonation, allowing optimal engine timing and performance.

Octane Booster raises the octane number of gasoline, which measures its resistance to pre-detonation or knock. Higher octane allows advanced spark timing and higher compression, extracting more power from each combustion cycle. It's useful for high-performance engines, vehicles experiencing knock, or when running premium fuel isn't available but is required.
