spark plug install problem hello, i just bought a set of NGK iridium IX plugs(TR55IX) and upon installing them they dont seem to get tight. they are catching the threads because i cant just pull it right out of the spark plug hole but it seems loose. i dont think this is normal know but my engine is cold and its 50 degrees outside so is it possible that this normal and when the engine warms up it will be snug?
