Well.....
you are dead on trusting the ngk brand name...i agree...always buy ngk
The difference between the laser's and the none lasers is that the laser's have a platinum or iridium chip laser welded to the ground strap. That's what makes them last forever and a day. They used to be a platinum chip so if you were running nitrous you had to go with the regular iridiums because nitrous makes platinum spatter but my understanding is that they recently changes the laser iridiums to use both an iridium center electrode and an iridium chip laser welded to the ground strap.

Also, I know this guy well. He owns the parts store, I used to tow for them, and our shop is a good chunk of their business. He wasn't trying to sell me anything.
