"3951" is the NGK stock number for the TR55 V-power. Reason I posted it is sometimes parts stores look up the NGK plugs for our cars and say they can't find them - sorry for the confusion.

Why use those..your plugs tell you what is going on inside your engine..I like to look at mine regularly..I change mine every 8,000-10,000 miles..TR55's at a $1.68 a piece you might as well do it...I can change mine in 25-30 minutes..gap them at .055..
