Time to replace spark plugs in the everyday cars. Close to 60K on each and
never missed a beat since we've had them, but it seems like a good idea - and
yes, I've regretted that statement before =8~0
Since plain old OEM plugs seem to hold up so well nowadays that's my usual
choice. Is there any other advantage to platinums besides life ?
Is there anything new in plugs that's worthwhile ? I saw some
double-side-electrode plugs at one of the chain parts stores the other day
(don't remember the brand). They looked like aviation massive-electrode
plugs. But don't multiple electrodes require an ignition system to match
their power needs ?
The cars - 1999 Ford Mustang Cobra with a DOHC 4.6 L, and 2005 Yukon with a
6.0 L
Thanks !
