First off, I think you should move this to the general section under Montero Sport, since you are, after all, driving a Montero Sport, that will help you get a better answer as more people will see it. Being this the Montero only section, not many people, unfortunately, venture down here.

Who did the spark plug and wire work? Yourselves or a dealer?
