Should Have Bought Local

I have used these plugs before. They worked great. Got to my place on time and in good condition. It is nice to speak to an American in this country when ordering things.

I could hear a difference almost right away once these were installed. Only took an hour due to removing all the items to access the engine, but once in they were a game changer that is for sure.
