I have been running NGK TR55s for a while now at .060 and am going to change plugs when installing the headers and y pipe. With the mods listed below, what do you guys think the best gap would be for me on my next set of TR55s? Thanks in advance.

 

I just purchased some 55's today and im running mine at a smaller gap at .045 because of the spray. It seems to be running smooth at idle and W.O.T, so Im guessing any where between there and what you had it at is fine.

 

Cool, I think I'll gap em at .050, if anyone else has any other opinions on a gap I'm all ears, I should have a little time before the headers come in.

Good info, thanks blackss. BTW, I see you are from Midland, I had a friend that knew someone up there with a black SS that was supposed to be running twins under the hood.

 

Thats not me. I was the one that posted in the TX section about the gathering about 3 weeks ago. I'm still in the process of getting things straight. There are so many different car clubs here and they're like gangs. If you're not with them, they don't like you. I think I can get it straight though. I'll let you know whats going on in case you and your friends still want to make the drive.

 

Yeah, just wondering if you knew him, I can't remember his name but I know his car. I am in Sweetwater now, but might still be interested in going down there for a GTG, just let me know.

 

Don't know him but there is a black Z28 in Odessa that has a turbo. Not sure if it has 1 or 2 though.
