Latest Spark Plug TSB #?

I searched for the TSB for my 05 and couldn't see anything? Where can I find a copy of the newest one?

I've been reading through the old posts on plug changes and trying to do my homework before I attempt mine.

What do the majority think is the best replacment plug? (Champion 7989?)

Thanks

Thanks for the link, I thought there would be more to it than just backing them out and using aero-kroil.

There is a newer one than that describes the updated tool for removing a snapped off porcelain and says to use a Ford branded chemical (carb cleaner maybe, can't remember exactly) instead of the Kano product.

Someone posted a link to it a few months ago, but I don't think it has made it to the database on this site yet.

Search for TSB 08-7-6 on the 'net, and you'll find a few hits that have links to the TSB.

I think the new TSB also recommends removal on a cold engine not warm to the touch.

Does anyone make a recommendation on a better replacement plug? Ex.: Champion #7989 or Autolite #s HT1 or HT15. The Champion plug is a one piece plug.

Is the Autolite 1 piece?

The Autolite is a 2 piece plug simular to the Motorcraft. Denso has a new iridium plug (5326 or IT20), has anyone seen and/or used these?

I have not used the Denso plugs in my F-150 but I used them in a SVT Focus I owned. Dyno showed a 3 h.p increase with just the plugs and the engine idled better. I always would dyno the car after each mod so I would know what each part offered. If the Denso Iridium plug is a one piece for the F-150 then I would not hesitate to use them.
