Sparkplugs/Hydrolock/Release

[Lost Soul]

Has anyone ever heard or used a sparkplug that prevents against hydrostaticlock and detonation in their ATV?

I just heard about these sparkplugs that are designed with points to break, and release the cylinder contents to prevent sever engine damage.

I was curious to see if anyone had anything good or bad to say about them. Or if they effect performance in anyway.

I found this web site for them http://www.prepsparkplugs.com/home.htm
