As probably seen on my previous posts I am doing the 6k fluids service on my 1198. I was going to do brake fluid, coolant, plugs, oil and filter but looking back at the last dealer service 1800 miles ago the coolant and brake fluid where done so I will leave them. The plugs where done at 2200 miles so I will change these, however I was under the impression they where NGK mar10 but the last set fitted by the dealer where NGK cr8eix, so,what plugs are right? Is there a reason why they are different? Thanks.
Mar10's are the correct plugs. I've seen conventional plugs used but even so, the 8's are way out on the heat rating.
My mistake, the plug was for another bike so not fitted during service! Just ordered a couple of mar plugs
