First i would like to make it clear that i have fired my Triumph many many times in sub-zero weather with perfect results. A couple three times i noticed a slight delay. This delay was so short, i kinda think it didn't much affect the shot.











What i did to the Triumph plug is make the cavity on the end some deeper, so it was more like the Omega plug. This was done with a 82 degree 5/16" center drill. This destroyed the flash hole, so it had to be replaced using a vent liner. The flash hole diameter in the vent liner is the same as the flash hole in the new Triumph plug, which is 0.028" to 0.029".
