Saved another 2011-2016 LML Duramax Turbo the other day, the factory air box filter grid is a known cause of turbo failure. When the air filter gets restricted the plastic grid breaks and sends plastic pieces into the compressor wheel creating an expensive turbo replacement. The DHD Turbo Saver is a great preventative upgrade on any 2011-2016 LML Duramax!
