I know this topic is ot but I just wanted to see if any of you have new opinions on these plugs, in case some of you decided to give them a try. It's tune up time for me, so I was thinking about these plugs. Thanks.

 

Please do a search, this has been covered before.

Stock plugs are more than adequate for all but those with lots of pressure in their combustion chamber.

 

Also dont post in more than one forum.
