Worked great in my 1999 Infiniti QX4
Easy installation, good price, feels like high quality. The car is running well now. The packaging could have been a little better (the Amazon worker put them in a larger cardboard box, so they fell out of their individual packages).

Can't go wrong
Good plugs for the price. I've heard these are "iridium enhanced" plugs and not pure iridium. Plus the platinum puck (or whatever you want to call it) on the ground electrode is either just a coating or barely there. In a nutshell, these leave a lot to be desired when you compare to OEM.But the truth is, these do fine for most vehicles as aftermarket replacements. Why? The OEM plugs ('07 Kia Sportage 2.7L) lasted 180K (most people don't change them). Drop these in at 180K and guess what-- they'll go to the graveyard with the car. I have utmost confidence these plugs will last 50-100K+ quite easily.

1996 Miata
Replaced a set of basic NGK plugs on a 1996 Miata with these iridium Autolite plugs. Noticeable improvement in startup speed and engine smoothness. Exhaust sound changed, slightly more burble and distinct sounds when shifting (full catback exhaust). Overall these are great plugs and came gapped correctly for my Mazda.

Works
This particular prt num (xp3924) fit a 2003 Land Rover Discovery. My previous plugs had 90,000 miles on them and seriously impacted my fuel economy. It had detoriated to about 12.8mpg average. Now it's been restored to about 14.5mpg average, which is good for a Land Rover and every bit helps! I don't believe the 'iridium' style plug had any impact if the fuel economy, it's more of feature to help with the longevity of the plug.
