What spark plugs CL203/C180K coupe

[MORGANpl]

Im will be replacing soon the spark plugs. I always use on my other cars NGK Iridium and I was happy with them. Dont see NGK is doing them for the Merc. So what other options I have? What would you recommend? Bosch,Denso Iridium,NGK??

If it's an M271 engine.... then NGK Iridium ILFR6A is your plug.

Available from either NGK or from MB - A 004 159 13 03.
