New ignition coils

Last year, the car was stuttering at low RPM. Since there were no codes bring thrown, it took a while to diagnose. After the car finally thew a code, we figured out it was a bad ignition coil. I replaced that one with a new Bosch OEM coil and all was good. Until recently. A couple weeks ago, it started again. This time, because the car is approaching 100k miles, I decided to replace them all. Instead of going with OEM Bosch coils, and on the recommendation of ECS Tuning, I decided to go with the new Dinan coils (at half the price). Easy install with my son.

He did one side (notice the recently replaced coil at the back)…

While I did the other…

The new ones looks shiny and new.
