Ordered a new set of sparks for CLK320 W208, but when I look, I've actually been sent the resistor spark plugs: FR8DPP33
So far as I read everywhere Mercedes specify F 8DPP33 - no R for resistor is mentioned...
Are the resistor plugs perfectly ok, or will they perform worse than their non-resistor counterparts?
Regards,
Nathan
