Since the regional technician wanted to make an example out of my installing an aftermarket charge pipe they denied my claim. Cylinder 6 is beat to hell. The engine grenaded 700-800 miles after the installation but the BMW RT put his foot as far up my ass as possible and I'm just not able to fight a legal battle against goliath right now. He claims I dropped a bolt or something in the engine during installation. I know I didn't. The car is now at an independent shop. I'll leave it at that.
