No such thing as a TR-8 Maybe an NGK 8 but the box denotes nothing of the such of TR anything, anywhere on it.
Generally the folks are using R5671A-8's, 9's, or 10's depending on fuel and power level you are looking for. One of these days, people will figure out the denotation of tr only pertains the 5's, 55's, and 6's...As in TR-55, etc.
