Colder Plugs/ Not spraying

My question is, if u install a one step colder plug in a daily driver and dont spray it all the time will the colder cylinder temperatures hurt performance, Realistically its like putting a colder plug in a car without spray.

I saw a 1-2hp loss na when switching to 1 step colder plugs. 1-2hp is in the range of error....ie temp change, humditiy etc. So I would say any performance loss is completely negligable.

Yes, colder plugs are perfectly safe to run. If you went drastically colder, 4-5 steps, you could experience issues with the plugs fouling from unburnt fuel buildup, but that would be the only real negative effect, and it would have to be a large drop in heat range, not 1 or 2 steps.
