Absolutely great!
Installed these in my 2019 Kia Forte and I can honestly say when I took a test drive I felt the difference right away. Smoother take off & I can tell the engine performance is way better. The installation was easy and as long as I have a car that needs this exact spark plug, I will be purchasing again!

Works great in my 2015 Jeep Grand Cherokee Overland, 3.6L
Replaced what I think are the OEM plugs at 197k due to P0300 Random Misfire code. Found Cylinder/1 - Bank/1 had a broken electrode. Replaced all 6 with these and the truck runs great now. Also replaced all 6 coils at the same time with NGK, just to be sure. And according to Reddit these were recommended for my model/year.
