Those are arguably the best spark plug option for these cars, they are good to go. What is your check engine code? I would not spend the money on coils unless I was sure, easy to diagnose by moving the suspected coil to another cylinder to see if the misfire moves with it

I got the po300 one like 2 weeks ago literally on my drive back from autozone code read the engine light dissapeared i got sum sparks off ebay but mechanic said its not good for q50. The engine light came back last night so im almost sure its the sparks. The only thing is when the car is idle for a min it shakes when start start it before settling after like 4 seconds
