I just finished up the new website for O'donnell Glow Plugs "Version 2". The new version is even better than before. To answer any of your questions please visit the website. The Odonnell team went through painstaking effort to offer you a nice comparison chart that allows you to pair up your old O'donnell Plug to see what is comparable with the new line up. It also allows you to compare competitors plugs with the new Odonnell line of plugs. And even better yet, Marine plugs can be purchased direct online right from the Odonnell team themselves making access to O'donnell High Performance Results just a click away.
