Our E92 shop car features top mount Xona Rotor twin turbos, along with a plethora of one off items built with performance, and reliability in mind. This car is running a custom one off cooling system that allows the cylinder head to be cooled before the block to help reduce steam from being trapped in the rear of the head. This cooling feature also helps keep the OEM direct injectors cooler temps than they normally operate at. Force cooling the head also keeps OEM coils from dying. This modification has allowed us to run OEM coils and injectors for over 50k miles!
