Re: TR55 IX, Iradium tip?? (Blues77)
TTT, I also checked the old plugs (Ac delco), and they dont look that bad. Whats the correct gap? Cuz the AC was about .05 smaller then the TR55IX, and the box says not to gap the NGK's. Just want to make sure these will be ok, before I put in... Thanks

Re: TR55 IX, Iradium tip?? (Blues77)
I put these in over the summer, you don't gap them (TR55 IX). I noticed that my LT4 revved up a little quicker and started up a tad quicker with them. My OEM AC platinum plugs lost the little pucks on them at 16000 miles. That is why I went with the NGK's.
