Same here. I only prefer the autolites because they're cheaper though. I noticed no difference from brand to brand in terms of performance, idle, or life.

If you have a forced induction or huge shots of nitrous, I'd go with a Denso Iridium plug. Start around an IT22 or IT24 and see. IT16 is stock heat range and IT20 is equivalent to a TR6. I thought about doing IT20s for my car... maybe next time.

I pulled my TR55's from my 5.3 a couple of weeks ago, they had about 40k or so on them and they still looked new. I'd run NGK's but a spark plug is a spark plug, as long as the damn thing works.
