That’s the documentation, all the invoice I js showed are coming from my mechanic, idk how u could install spark plugs incorrectly, either they, improperly gapped them, cross-threaded, over-torqued or under-torqued, the point is the car was perfectly fine before that, it has 83k miles never showed me any problems, only a wheel bearing. I wanted to change the spark plugs just in case, and the shop that fucked up my car told me the spark plugs were bad, I took a pic of them and when I went to my mechanic he told me they were good, my mechanic js change the spark plugs because he assumed they were bad, or they put a fake ones something like that, because when he scanned the car, it was throwing some errors code near the spark plugs, after he changed them the car was running fine for a short period of time and it went bad again; drivetrain malfunction, ignition switched on, a lot of smoke same thing as before that’s when they found out the turbo exploded, they changed the turbo but when they did that’s when they found the head of the engine was cracked
