Iridium Spark Plugs

I was wondering if anyone has used the NGK or Autolite Iridium type plugs in thier V-10? I put a set in my Chevy and it dosent throw any more random misfire codes and starts up great now. Was a little hesitant to try them in my V-10 cause Ive heard alot of problems with the blow out thing...and backing out...ect. Kust thought I would throw that out there and see if anybody has tried them. Otherwise I will just use the Double Plat MC. btw its a 2003/superduty.

Thanks!!

Only use the Motorcraft plugs with the V10s.
Use anti seize and torque them to 180 inch lbs.

They will never blow out as long as thats done.

Anything else is taking a risk. I have read these trucks really don't like NGKs.

I have not, mainly because the Motorcrafts work so perfectly well in these engines.
One of those rare "ain't broke, don't fix it" moments for me!

I never tried NGK's but I did have the misfortune to put Bosch DP's in my F150. I'll never do that again.

I have the NGK iridiums in mine, works just fine. Put them in ~10k miles ago, no blow outs yet, no starting problems, etc... No effect on mileage either. Could have put the extra 40 or 50 bucks they cost over the platinum somewhere else, but oh well.
