## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by K***E on September 25, 2025*

Excellent for. Performance of vehicle improved. Gap was preset and installed easily.

### ⭐⭐⭐⭐⭐ Perfect OEM Replacement
*by W***S on June 17, 2025*

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.

### ⭐⭐⭐⭐⭐ Autolite Iridium XP in a John Deere LA120 riding lawnmower
*by D***N on June 8, 2024*

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!
