Does my plug gap need to be altered and can I use my existing plugs?
Does my plug gap need to be altered and can I use my existing plugs?
Nitrous oxide increases the pre-combustion pressure, which means more spark strength is required to jump a given plug gap size. With ignition systems that have spark strength which is border line or inadequate, reducing the plug gap will make it easier for the spark to jump a gap and fire the charge.
Stock spark plugs can act as a glow plug due to the higher cylinder temperatures that nitrous can cause, resulting in pre-ignition, therefore it is essential to replace the original plugs with a suitable grade harder.
