To try to answer everybody at once I will try to explain the X plug. It was first used in Nascar because of ground straps burning off or breaking off, they are made by both Autolite& Champion in limited heat ranges and numbers .They are used by just about every team. They are available 708 tapered seat & 3/4 reach gasket seat. The best part is no need to index. These plugs are made in limited runs so are hard to get sometimes.
