[QUOTE="Richard L, post: 998062, member: 52972"] l1tech, Good post and interesting to see different perspectives. As with anything, when a little dab will do, people think that a bigger dab will be even better. I have used anti-seize compound on the treads of spark plugs going into both cast iron and aluminum head for many years an have never encountered any problems either in removing the plugs or in the plugs not grounding. A small dab at the bottom of the thread will lube the treads and the metal body of the plug base will properly ground the plug. That may be a different story with the new 2 piece spark plugs, since the threaded part is bonded to the rest of the plug and that bonding agent may interrupt the ground if the threads are not making a good ground?? I just don't understand why auto makers have switched to the two piece plugs when they could have made the same plugs in the older one piece design that would work just as well....There does not appear to be any advantage to making a two piece plug and it has caused a lot of problems and confusion. ...Rich [/QUOTE]
