Quick Overview


Thunderbolt Glow Plug - Heavy Duty Thunderbolt



Thunderbolt Glow Plug - Heavy Duty Thunderbolt Glow Plug - Heavy Duty Thunderbolt

Thunderbolt wanted boat racers to have a plug that was more durable when using a pipe, running at high RPM, and even at high temps.

The Heavy Duty plug is perfect where a reasonably-high idle is no problem but reliability in challenging conditions is demanded. You'll find this plug durable when using tuned pipes and higher nitro fuel. We recommend this for all car engines that use a standard (not Turbo) plug.
