Great Replacement For Less
I replaced the original equipment NGK iridium plugs in my 2002 Acura RSX with Autolite iridium ones and noticed no drop off in performance. After 46,000 miles with these plugs, the car runs great and my gas mileage is as good as ever. The Autolite plugs cost less than the NGK plugs.

Good Replacement for OE NGK or Denso Spark Plugs
Got some Autolite XP 3923s for my Toyota Sienna 2001. And they seem to work fine. Fast start, smooth idle, and the engine runs just like using OEM NGK or Denso plugs. But these are considerably cheaper and come with a 5-year warranty. I was afraid the end of the plug was going to have a strange head that would cause my Sienna ignition wire boots to slip off the end every couple of days. But the head was similar in a shape to the dealer installed Denso long life iridium SK20R11's. Moreover, ignition wire boot slipping off won't happen on new Toyota vehicles, which have separate ignition coil/boot pairs for each pair of plugs (3 sets for a V6 ) and these are each screwed down with a 10mm x 40mm long bolt to the engine block. So no slipping fears at least for me. Also, I can report no noticeable decrease in mileage. It was really simple to replace 3 front plugs, while changing out the back 3 is difficult due to restricted access, which is why I hope these will last a LONG time. We'll see how the 5-year warranty holds up.
