Gap??

[VinPecora]

Plug gap for stock 87 Gn is??? And are the Cr43's the plug that came in them from the factory??? Thanks

Should be .035. I think stock is a little hotter @ r44ts.

 

[QuickWE4]

r44ts = stock plug
cr43ts = one heat range colder with a heavier electrode

gap either to a tight .035



BTW - anybody else have a heck of a time finding the cr43ts plugs? Hell, when I finally find a shop that has them in stock, I buy oodles of them.

What should I use??? 44 or 43 I have a few bolt ons, will a 43 be better, why?? Or any one think I should use another plug?? THANKS

Check gnttype.org...I think 43's are recommended for cars running mid 13's or better.

Depends upon your setup. I run the cr43's with my setup- TA51, THDP, 009's, BM cold air, Walbro 307 h/w, blah blah blah blah.
