Switching to a hotter plug...wishful thinking

[Matthew A.]

I noted that champion makes an inductive plug, a QL-16 V. The "Q" denotes it being an inductive plug. My particular Force uses a UL-18 V. Would the switch to the hotter running "QL-16 be too hot. According to Champion, each increase in number denotes an increase in combustion chamber temps. of 70 to 100 degrees C. or 145 to 212 degrees F. Something tells me the answer is pretty much self explanitory. I'd risk it, but I'm fairly certain JB weld doesn't work to seal the tops of pistons. lol

I would not try it. Force motors overheat easy enough on their own without you courting disater. Hotter heat range plugs may have some benefit if you spend a lot of time trolling. Another issue is the distance the electrode is to the piston. In some cases the hotter plug goes farther into the cylinder which could cause the piston to ram into the plug.
