First recommendation: Identify which of your old coils are bad. Just disconnect them all one at a time while the engine is running and you'll see which one doesn't slow the engine down. Leave them and throw away the rest. These QYL coils will eventually fail, but like your original coils, they won't fail all at once. However, they fail much faster than the original ones. Returning your old car will help buy you time so you don't have to make hasty decisions, or worse, stop driving until you get a new one. I keep mine under the spare along with the minimal tools needed to change it. I bought them in June 2018 and had to order another set in January 2020 after one coil failed then the second if I remember correctly. Thus, the entire set could last 18-19 months before the first failure. This time I bought another Revain kit from AA Ignition. Decided to see if another brand would last longer. It's been almost a year now and they're doing fine so far, but only time will tell how they compare to the QYL coils.
