Great product with better power distribution than regular spark plugs
These are great! Worth the money. After changing them out, it took care of the stalling at Red lights.

Autolite Iridium XP in a John Deere LA120 riding lawnmower
I replaced the 2 champion spark plugs in our John Deere LA120 riding lawnmower with 2 Autolite Iridium XP3924 spark plugs and it has never started quicker. It has over 200 hours on it and even when new it did not start so quickly. I have mowed our lawn twice (over 4.5 acres) since installing these Autolite Iridium spark plugs and I have not had to refill the gas tank. In the past I could get 1 and 3/4 mowings on a full tank of gas. Being Iridium spark plugs, these will not need to be replaced anywhere near as often as copper or platinum spark plugs. These Autolite Iridium spark plugs would be well worth the price just for the longer replacement intervals but factoring the quicker, smoother starts and lowered fuel consumption make these an even greater value!

Perfect OEM Replacement
No need for gapping these. They're already gapped form the factory. They fit right in my 2002 Chevrolet Prizm. Installation was a breeze and they seemed to be of good quality and function exactly how they're supposed to.

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.
