TR6's on stock truck?
Hey guys...........I just thought of something.........when I traded in my truck, I turned it back to stock, but left the NGK TR6's in there from when I had my 4# pulley...........Do you think whoever bought my truck will be ok, or should I track 'em down and warn them...............would there BE any problems, or are those plugs ok to run on a stock truck
thx,
jc
