Since I am a new DIY. I have a few questions. Like what size socket for the SparkPlugs? How and what does the SparkPlug tool do that comes on the hood rod? Do you have to do anything special to the plug before you put it in? Patrick Sherman 1997 JETTA GLX / 26k / Tred Eurospeed Motorsports Email:patrick@eurospeed.org http://www.eurospeed.org
