Hi all - I am now due to replace the spark plug which is currently a Champion N4C. Can anyone tell me please of this is the best one to replace it with, or is there a better one on the market?
Many thanks and Happy Easter to all
Paul

Drags suggest the NGK B8ES, take your pick for equivalent

the N4C seems to be the goto plug for most Brits with the slimming down of options nowadays

Many thanks Chaz- that gives me something to follow up
