My mechanic who did my plugs recommended the auto-light double platinum (APP104). I don't sell very many of these E3 plugs at all. Seems the Boss Hoss guys love them in their bikes with the 350.

Ford modular engines prefer Motorcraft or Autolite spark plugs. If you change to e3 plugs and have a miss, I hope you have enough money left over to buy the Motorcraft or Autolite plugs. If you don't have a miss please report back here.

Do yourself and your wallet a favor and just get 10 Motorcraft SP479 plugs and done. The E3 is an overpriced chinesse made plug without a proven track records. Every one of these gimmick plugs I've tried didn't deliver. Remember the Splitfire plugs?

And just to qualify where I'm coming from since I'm new here, I've been a motorcycle mechanic for about 18 years now, mostly working with HDs, currently working at a BMW specialist shop. I've built a few motors along the way, including the one in my Buell- 108rwhp & 112 lbs/ft out of a stock bore & stroke Sportster motor (1203cc aircooled pushrod Vtwin, for those that aren't familiar with HDs). I'd like to think I've got a decent grasp of what goes on inside a motor.
So, back to the question at hand. Does my V10 actually "prefer" one brand over another? If so, why?

The short answer, apparently, is "yes". There have been numerous posts here from people who had put in new plugs only to develop a miss a short while later, particularly with Bosch plugs. Put in Motorcraft/Autolite plugs and the miss goes away.
And since the V10 plugs can be problematic to change, you don't want to do the job twice.....

Not sure if the plugs in this previous posting were the same ones. I would stick with Motorcraft.
