Hi, does anyone know if the F8KTCR spark plug is a resistor plug, I need to replace these plugs but they have been replaced by FR8KTC+.

I know the replacement plugs are resistor type and do not want to put then in if they will damage the ignition system.

Thanks
Ian

F8KTCR is a resistor plug. The "R" in the part # = resistor.

Thanks for that, I was wondering what else the R could be. It's just that on the Bosch website (pic attached) it doesn't say it has a resistor, unlike the newer one.

So I should be ok with the newer replacement type then?

Thanks Fritha, Mine is a later 1997, under the bonnet it says to use F8KTCR so think I will go with the new ones now I know the old ones are resistor plugs.
