Don't get me wrong NGK aren't bad but I've always used Duraterms and they've always outlasted my ownership of the car.
My Datsun has NGK spark plugs in just because they're rated by all the Datsun-200 owners for perfomance (copper over iridium and platinum).
Not that glow plugs / spark plugs directly correlate..
