Installed my new set of NGK-LTR7IX-11 plugs this morning. They all came gapped at .034" and I regapped to .027" and reset my KAM afterwards. I have a 13' that I got in Sep of 12' with roughly 7900 miles with Torries 93B tune. Instantly I felt a much smoother idle and initial roll into the throttle. Didn't really notice any extra additional performance, per se, but I did notice a few MPG increase over about 60 miles than the previous stock plugs. Also when fully warmed up I notice that the oil temperature gauge, as expected with a +1 cooler range, is a little lower than with the stock plug. Normally when fully warmed up with the stock plug it is just a tiny tad below ½ way. With the 1 step colder plugs it never got above 3/8's. Took some pics of the factory plugs. They looked pretty good, with normal carbon. They were ALL however gapped at roughly .020" which might explain the sometimes weird idle or slow initial roll into throttle I've been feeling.
