TR 55's should be left alone ...right ??
When installing the TR55 it is common to leave the gap alone right....not to open it up to factory settings ?
Thats how I installed them in my LS1 Firehawk w/o problems.
thx Tim

That's what I did on my basically stock, headers and intake, Z06 and they seem to work fine. Mine came at about .055. This time I'm thinking about bumping them down to .050 and trying that. Oddly enough the NGK web site says to set them at .044 and I kind of doubt that. I'd like to hear a definite answer to where to set them.
