What do you think of this plug?

I've run NGK's almost exclusively for the last 20 years in my MoPars ; I say almost because of a momentary lapse in judgment last Summer ...

I found a box-of-8 #405 "Champion" plugs in my storage , and since my 'Net needed a set of freshies , I popped 'em in after setting their gap @ .040 .
Boy , did my car run like **** ! Ran so horribly in fact , that I just cleaned and re-gapped the old Autolites that I removed , and strapped 'em back in after one week !

Those crappy "Champions" lost their gap in that short amount of time ! Some had 'bent' to .030 , whereas some had 'bent' to .045 !!

Went back to my beloved NGK's , and have not looked back .
