While I had a new set of plugs on hand, for once I resisted installing them so as to not change more than one thing at a time. First impression, beginning with a stone cold engine, full rich on the mixture, two hits of primer, hit the starter and it came to life immediately. I mean that it started quicker than my Mazda 3 or my Chevy Silverado when doing a cold start. It idled down to 1500-1600 as sweet as could be, unlike previously. I didn't have time to fully warm it up and do a full power test, but I did run it to a little over 4000 rpm and it ran very smooth. So, bottom line is that I am happy with the LS2 "Yukon" coil upgrade. I will post a flight report after I get the wiring cleaned up and flight worthy.
