These spark plugs saved me a really expensive bill. Prior to purchasing these, I had bought some NGK Iridium Spark Plugs to put in my 2015 Kia Soul 1.6. As soon as I did my engine started to hesitate and buck, and the check engine light came on. Went to Autozone to run diagnostics on the car and it came back with a bunch of random codes to do with the coils and spark plugs. I was really careful and meticulous about doing the procedure so I know I didn't mess anything up, specially not all four spark plugs/coils.
Went back to Autozone and bought these Bosch spark plugs and it immediately made the car better. Drove it down the highway at 70mph and the car is running completely fine, whereas before I couldn't get it up to 3rd, up a hill, or go anything faster than 20mph.
