Nah, that requries someone to do something, then relies on someone at the other end to take some notice, and then also do something. Far to many chances to fail there. Best thing to do is let them do the service then check that they have put the correct plugs in. I find that if you try to tell them stuff beforehand they get all superior and pay no attention, after all they're Suzuki, what do we know?
After having an Indi. do the interim 4k service I was going to have Suzuki perform my 7,500 one for the stamp as I could be swapping it for the 1000 in a couple of years and it would look good in the service book. However, in light of this I don't want the hassle of actually trying to make sure they fit the correct plugs. I can't believe Suzuki haven't issued an urgent correction, and if they have, why some dealers are ignoring it.
