[Ford Man]

I've been using platinum's for several years now, usually Bosch and have had several sets last over 100K miles without any drop in FE. There has even been times they had so many miles on them I would just go ahead and put new ones in even though the old ones were still firing fine. I recently put new plugs in my '88 Escort and I think the old ones had about 150K miles on them. If you'll look at my gas log you'll see where I got over 48 mpg a few times on the old plugs. The only reason I replaced them when I did is because the insulator on one of them cracked and it was jumping fire. $25 is a little bit high for a spark plug when you can buy a good platinum plug for about $2.-$3 each. Even if they were better plugs I don't see ever making up the difference in fuel savings when you figure $100. vs. $12. for a 4 cylinder engine.
