at 90k miles i decided to give Denso a try, but which one and why? Thanks,
Stock A/C Delco 41-103 gap is 0.043
Denso ITV16 gap is 0.040 which is the suggested plug here.(smaller gap)
Denso ITV16TT gap is 0.044, i would think this is a closer choice? (hair larger gap)

Owner's manual for my '04 says gap should be 0.042". That's no help, but just wanted to show off the fact that I still have my Owner's manual for my 16 year old truck! Whichever you decide to use I'm sure will be fine. Obviously, don't try to adjust the gap, you'll damage them for sure.

Get the TT plugs. It's Denso's newest technology. Also, be careful adjusting the gap on Iridium plugs. The tip is thinner than a strand of hair and can be easily damaged.

well my dyslexia was in full swing when I typed the info lol . The ITV16 is 0.044 and ITV16TT is 0.040. Sorry for any confusion.
DB- gotcha, that would explain why I came up with only 1 hit with our search engine. These should work well with the SuperSparkz delete kit I just purchased from James. :)

They'll work perfectly with the super sparks. The older Densos worked great too
