Not Ranked
Does not increase octane rating, cools the intake charge to help reduce pre-ignition, keeps the combustion surfaces a lot cleaner, reduces the total amount of available energy in the intake charge by reducing the total volume of fuel/air mixture (displaces fuel and air in the intake charge), but you might be able to make it up through more timing advance.
