Fast Glow Plug - Large Thread Replacement for Series Glow plugs up to 1979

New MONARK Fast heat glow plug designed to replace the series loop tip style glow plugs that were installed in all non-turbo diesel engines up to 1979. These have the large thread built in so they will install directly into the older heads. You can purchase this glow plug separately or in any number you need. Just change quantity in your shopping cart.

IMPORTANT NOTICE: If you are going to install these you must undertand how they need to be wired differently and how they will respond with your current relay or pull starter. If you do not, then I suggest you purchase one of our kits with instructions. If you already have a conversion and need a replacement glow plug or you understand how to convert your series system, here is your chance to order these individually. NO instructions are included.
