No, its more like a glow plug on a diesel, it gets hot with an igniter but once the fuel is first ignited it stays hot and keeps the cylinder firing. A spark plug needs a constant pulse of electricity.

Have a look at http://www.modeltechnics.com/glowplug/firepower.html to learn more about them. The test results on various engines/fuels give a good idea of why it's important to use the right heat range plug.
