I want to buy some spare spark plugs for backup use on a holiday abroad.
What is the best spark plug for a 1997 2 litre turbo petrol XM engine?
It's a VSK estate car with auto gearbox.
I have a preference for NGK plugs.
I don't want expensive 'boy racer' type spark plugs, just reliable ones.
There web site tentatively recommended the NGK BKR6EK version.
Any suggestions?
Regards,
Rudge
