### ⭐ 1.0 out of 5 stars







  
  
    NOT compatible with Mitsubishi Outlander GT or other high-temp engines
  

*by M***Y on Reviewed in the United States on April 25, 2018*

These spark plugs literally started melting when installed and used in a 2014 Mitsubishi Outlander GT (6 cylinder).  My GT first startted faltering when cornering after several months and recently had an enginer code indicating bad spark plug in #5 cylinder.  Three of the six olugs had significant heat damage when removed.My mechanic (whom I did not consult about these spark plugs - lesson learned) told me that the Autolite plugs are notorious for failing within 1-2 years.  I would not recommend ourchase of these plugs for any application.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Easy install, smoother performance
  

*by T***N on Reviewed in the United States on July 14, 2017*

Fast delivery. After 67k miles on my 2013 Kia Optima I noticed an immediate improvement. Runs smoother and more responsive. Nearly as easy to install as a lightbulb!

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    These spark plugs are very good. The functioning of the car is very smooth ...
  

*by H***A on Reviewed in the United States on December 1, 2017*

These spark plugs are very good.  The functioning of the car is very smooth now.  My dealer was quoting 240$ to have four spark plugs changed.  I did it myself for under 50$ including the cost of 4 spark plugs and the required hardware.
