I was always told "use OEM plugs, always. If it came copper use copper, if it came platinum use platinum. Don't use Autolite if it came NGK (or whatever the brands.)" Okay makes sense. Obviously, non stock cars may have other considerations. Now, being one that doesn't take "just bein...

It's a little strange to see "keep it like it was made" in a Performance forum, where just about everything revolves around what we can do to make cars better, faster, stronger, etc. If there's new technology that can improve the life cycle, driveability, joy and fun of a car, why not use ...
