If there is positive pressure inside the cooling shroud, wouldn't these seal better if they where pushed inside the cooling shroud? I've always installed them on the outside. Do you?

...Until they get brittle from the heat and then break off inside the shroud the next time you pull a plug wire...
You can put them inside if you like - I am not the spark plug air seal police. Since T-IV sheet metal is curved in that area a good seal is problematic anyway. "Supposedly" you can slide them up and down on the connector a bit to improve their loading against the shroud. Probably you'll find they're already too brittle for this. Some of the plug makers (Magnecore comes to mind) have nice seals of heat-resistant rubber with the small inner flange and a large outer flange designed to snap into the hole and stay there. I haven't tried them on a T-IV so I can't say they're actually better in this regard. |
