ttix plug gap and oil
About wrapped up with putting the ttix kit on! Needed some input on my spark plug gap on the tr6's. Shooting for around 15lbs or so. Also on motor oil to use and what weight! Thanks for any and all help guys!

I think TR6 plugs are gapped at 0.035 or 0.040 out of the box. When I ran the TR6's I used 0.035. For oil, I like Shell Rotella T 15W40.
with starting or using the 0.035 gap. IMHO There's better plugs out there then the TR6's though.As for engine oil I personally just use the good ole mobile 1. I'm not turbocharged though.
