I am currently running NGK FR5 plugs but they don't run good at all. I want to put some Autolites in but what does everyone recommend?
AP104, Resistor 25, AP25 Platinum or APP104??
Thanks guys. I am in the UK so limited to what we can get here. Looks like a choice between Autolite 25 is the only copper plug available to me so i'll give those a go!
