RE: best glow plug for TT pro 40
Yep thats right: OS puts out their specs indicating that the A3 is a hot plug and the #8 is a Medium to Hot plug. Seemed that that #8 actually runs a lower RPM than the A3. This makes one wonder why they are listed as they are. No matter what the manufacturer displays, the tests dont lie. Of course we couldve waited before running the plugs til the engine cooled back down.

Good heads up!
