A spark is a spark, as long as its not shorting down the plug, it wont make any odds at all

Thank you! At least someone has seen that these are a gimmick. If they were that good, wouldn't car manufacturers fit them as standard?

Petrols still shit tho

Just had to get that in there didnt you? haha

Tom a spark is a spark. you only get bad running when either the electrode is coated in oil (by which time, youve got bigger things to worry about) and it wont always spark or the electrode deteriorates and opens the gap right up. Tbh you would notice more of a difference in changing to brand new coil packs as these can break down and cause issues.
