Thunderbolt Glow Plug - Standard Short Glow Plug - Standard Short Thunderbolt
Intended for thin-head engines and engines that need reduced compression. Compared to the long plugs, these plugs have a shorter reach which works perfectly in some specialty engines that have a thin head. They also can reduce compression in standard or new engines that are a little tight at the top end. Engine running hot? Maybe this plug can cool it off without losing performance.
