Nelson Flat Element plug NL03
Nelson STD flat element style plug. Current stock is on a slightly tall body that is filled with additional glass. Requires both a head made to accept Nelson plugs and a Nelson plug clamp (part NL04). Nelson plug set ups generally provide a performance increase over standard glow plug configurations that have the threads for the plug tapped into the combustion chamber. Nelson plugs seal on a bevel outside the combustion chamber and provide a 'cleaner' chamber. $5.50 each
