Gasoline Direct Injection (GDI) engines are prone to early carbon buildup. Vehicle owners will notice a drop in power and performance, sometimes before the first oil change. BG introduces the new BG GDI Fuel/Air Induction Service which will remove carbon from the entire GDI fuel system in under an hour.GDI engines offer the performance of a muscle car with the fuel economy of a mid-sized sedan. GDI injectors spray directly into the hottest part of the combustion chamber for more complete, precise combustion. Add a turbocharger for a power boost and you have an engine that produces more power and fewer harmful emissions… with better fuel efficiency than traditional port fuel injection (PFI) engines.
