How long have your NGK's lasted

Well hears a testiment to how good they are. I've just replaced mine due to a miss-fire the other morning. When I whipped out the plugs they were *ucked but when I checked they had been in 19k !!! I know the iridium ones last about 40k but you get what you pay for.

Dunno, I've always changed mine every 3k.

Not that they have ever needed changing, but I do it that frequently because I want to keep an eye on things.
