It sounds like Autolite is finally marketing a fine wire plug. Autolite is the main vendor that suplies Ford with Motorcraft spark plugs. They have been supplying Ford with a fine wire plug since at least the 1996 model year. It has been original equipment on the Duratec V6 since then.

From what I can tell, the Autolite XP may be a better plug than the Motorcraft OEM plug. I'm pretty sure that the original plugs in my car did not have a platinum side wire.

There will always be a debate as to which is better, a fine wire plug or a conventional plug with a full sized center wire. I don't buy the "21%" bigger flame kernel.

It definitely would be worth trying. The biggest complaint I had about the Motorcraft fine wire plugs was the lack of platinum on the side wire.

I'm not sure that it would really be worth the difference in cost between an Autolite double platinum plug though.

I don,t think I,ll be the first to try these
I remember what happen with those split fire plugs

These look great! It's the best of the double plats - long life; with the best of the fine-wire: more spark. It looks like there is no more comprimise, these are probably the plugs to get. Gap 'em and forget 'em!

There are nothing like the Bosch SnakeOil plugs. There are no similarities whatsoever, so that comment was rediculous. Just because something is new doesn't mean it's junk.

What do you hope to gain from the plugs? Probably a less $ gone from your wallet than the APP764's?

The performance gain from double plats is probably close to nil, but most likely there. For me? I have new double plats, and I'll probably never change plugs again. If you're going to get new plugs because you need them, the $10 or so extra might net you a couple hp, depending on your setup. Before it was a choice between long-lasting double plats and a little bit more fire from fine-wires. I chose the ones I won't have to touch, others (Demon is the only one I know of) run fine-wires and change them more often. I would assume that less-stock engines will get more from the better spark, but I don't really have any tech on that, it's just a trend I've seen.
