Review on OCPTY Set Ignition Coil Compatible by Michael Richardson

I bought a Kia soul in 2014, which began to twitch at low speeds because coil number 3 failed. I figured why change 1 when you can change all 4 and not worry. The car works fine for the first week after replacing the coils and candles, after which the car slowly begins to stall. He's starting to stutter and shake like crazy so I'm checking everything, no codes are being thrown. Replaced all the coils with the old ones except one that broke, the machine works fine, ash? The bottom line is these coils were eaten cheap for some reason, spend your money and buy better quality parts.
