Much like society would crumble without a robust infrastructure, BMW’s pinnacle compact sports sedan becomes a pretty driveway decoration without the proper supporting hardware. The heavy-hitting S58 under the hood that moves the world-class suspension relies on a complex network of coolant lines and air channels that keep that twin-turbo straight six operating at peak performance. BMW may be known for their exquisite engineering prowess in their vehicles, yet some of the supporting infrastructure needs revision, especially regarding the charge pipes.
