Is there anything I can do to my car 3ltr s type converted to lpg that would make it more fuel efficient eg.different air filter or different plugs.When my car was being converted to lpg I was told that jaguar do special plugs,however due to them costing 150 pounds I just went with the standard plugs,would they make a difference

I understand jaguar do not do special plugs for lpg! Normal plugs are fine but will only last 15-20k max, the only spark plugs which will last for about 50-60k are Iridium plugs.
