BB,I have read nothing that said they put out a much stronger spark?I do not believe the spark plug can amplify the spark?Would it not have to be a Capasitor or coil to do that?What I have read is that the smaller tip puts less overall demand on the ignition system,which I guess means it has less resistance than a regular spark plug?I also believe that the material has a longer service life.I think that is about it.The electronic guru's on the board should be able to enlighten us about this stuff.I am not a big fan of super duper wammy jammy spark plugs,but when I read that the plug puts less demand on the ignition system my ears perked up!Watch how the counter people handle the spark plugs at your local auto parts store.I have seen counter kids grab loose individually boxed spark plus and drop em in a bag. I hand em right back to em and instruct them to get me another set and gently put them in a bag.Stupid kids think they are handling a bunch of nuts and bolts. Spark plugs are not made to take shock impacts. You can hairline crack the insulator and that plug is junk.So if you and I buy a set of twenty dollar plugs, watch how they are handled.
