I have the Autolites APP 104 now am going to compare them to the Motorcraft SP 479. Will get back to you on this. This afternoon I am going to instal new COP's and New SP 479's. Will update later.

 

you changed for the hell of it?? just knowing it was autolites annoyed you???

 

I have been posting for over a week on a different Thread.

I have big trouble with my truck.

Just doing research so I get it right the first time!!!

I don't like doing it twice, so I have started a thread or two, to receive feedback. Several of you guys, that have more knowledge than I do about these new mod engines, have been an excellent resource for me to learn from.

So that I don't make any mistakes while putting this thing together.

Thanks to all and I will update, hopefully with good news.

If I get it fixed I'm buying a round for you guys

Which Denso plugs are you using???
The one's listed on their website the right one's? IT16
Thanks!

 

The only plug Troyer sells are the Denso Iridiums, and the listings give good recommendations on which heat range to use depending on mods.

 

Yep I put in the Denso Iridiums [4mm] from Troyer also and luv them, no problems so far. mine came in the ignition upgrade package.
