Deletion of Reading spark plugs for racing/3

Comment: Sam makes a strong ''keep'' argument, but I wonder whether the treatment already accorded at Spark plug#Reading spark plugs is sufficiently encyclopedic and appropriately descriptive (though it, to be sure, needs cleanup as well); I don't know that the section is sufficiently large/distinct to merit its own article.  In any event, I think fairer analogies would be betwixt the Spark plug and Brain surgery articles and between this article and Brain surgery techniques, which, even if written consistent with |Wikipedia is not a how-to guide", we'd still likely delete in view of its being overly specific (we'd merge, I think, any encyclopedic information to a broader article, such as Neurosurgery or even a section of Surgery, and I don't think anyone would object to merging here, although I supported ''delete'' in view of my conclusion that there was nothing to merge
