What are correct Bosch spark plugs for a 2001 CLK320? Online search finds F8DPP33, FR8DPP33, or F8DPP332. The factory originals on the car are F8DPP222U which does not even exist if I search for it.

Any of those Bosch plugs are equal to OR have replaced the original Bosch number.

Thanks M.B.DOC.

Would the FR8 type be correct as well, given that the original plugs are the non-resistor type?
