        Great Plugs!

        Great spark plug, you get what you pay for. I installed this with the LiveWires and it's been working great. Make sure you go buy a spark plug specific socket and a 3/8 universal socket to make it a whole lot easier on that passenger side. Also use grease on both the wires and plus for premium seal.
