Not sure if this was an official NGK product, when I ordered picture showed what appeared to be a NGK stamp …. But pictures are worth 1000 words….. it was not stamped on arrival……
We live in a moderately warm climate and today after about a week being installed on my jeep temperatures got pretty high and the coil system decided the heat was to much, the jeep ran rough and missed … I swapped back to the old coil and it ran fine again, I believe I could have went with a cheaper version and got better results just my opinion…… thanks
