What does the Hot Spark Glow Plug N4 No.4 do?
A glow plug ignites the fuel-air mixture in a nitro engine. The N4 No.4 is a medium-hot plug suited for 4-cycle engines. It helps improve idle stability and throttle transition, and the element is designed to last longer than standard plugs. This pack gives you three spare plugs so you're always ready for a day of bashing or racing.
