Why do non-turbo 850's use a tri-electrode spark plug while turbos use a single electrode plug? What's the difference? Would there be any advantage or reason to use the tri-electrode plugs on a turbo? Thanks
In article , snipped-for-privacy@yahoo.com by polara dropped his wrench, scratched his head and mumbled,
The tri-electrode plugs helps defeat a problem that when cold starting, moving the car, and shutting off provokes a hard or no start condition on restart a few minutes after. The turbo motor uses a different heat range plug, has a different fuel mapping for cold start and doesn't seem to have the above problem.
No advantage that I know of.
