    I have seen some posts comparing different brands of spark plugs comparing the 6061 and the R5671A-10 and Autolite. I have also seen the NGK R5671A-10 for sale on several sites but some of them list a different "stock" number for this same number. My question is: Are the R5671A-10 plugs with different stock numbers the same plug?
