Any help would be appreciated. I had a spark plug ceramic crack while doing a top speed run lost half of the power at 200kmh. Pulled over and the car sounded like a wrx, putted home pulled coil packs found bad spark plug installed all new plugs now I'm left with this slap that you can only hear up to 2500rpm
