I dont know about the autolite, but i use the NGK's in my T/A.
Whatever you do, DO NOT use the stock GM plugs if you are going to use nitrous.

do you have an O'Reillys auto parts store close to you? if you do then go there and get the NGK plugs for 1.99 a piece and they come with a one year warranty and just take the old ones back and get the new ones when needed.

Autolites are a nice plug. Nothing wrong with them at all.
