In Florida this past weekend there seemed to be quite a few Glow Plug failures in flight, at least that was the buzz around the pits. It also helped me in a heat

I've had a stash of plugs that I have been using for a couple years, and its tough to wear them out if you don't go to lean, but the rumors were that the newer plugs were failing.

Anyone have any dirt on this???

I need some plugs for the season, but will stick with my used plugs if this is the case.
