NGK recommended the TR6IX for my setup no juice/blower just n/a on built top end. Around 12.3:1 static compression. I think one colder and close the gap about .005 should fit the setup or atleast be a good start. What do you think?
I heard raising the comp calls for colder tighter gaps but I dont know of anyone that has done it




NO plans for spray soon either Thanks for your comments

 

ive had nothing but bad luck with NGK's ... both TR6 and TR55's.... they had a crack in them, car started throwing misfire code..... just stuck with the AC delcos....

 

Any comments suggestions? Does this seem right to go 1 colder with my setup? And should I tighten the gap.005 or so?

 

The heat range seems ok with the high compression. The stated gap is too tight, stock gap is 0.05" and TR6 gap as I recall is 0.035".

 

TR6IX are in gapped @ .045 and wow, the plugs I had before must have either been junk or really just not right for my setup.
#1 It pulls alot better
#2 I got another 20-30+ miles to a tank.......NGKTR6IX

 

These are the iridium plugs one heat range colder? Wonder where I can buy them. I woudl think they would still be ok for nitrous use..platinum is not supposed to be good but iridium is supposed to be fine for turbo use.

 

Yup one heat range colder than stock. They are actually recommended for boost or spray. I think what helps is the electrode its not like normal ones its like a needle and I guess they require less of your ignition and provide a better sparK.
