The APR Stage III Turbocharger System produces an incredible 522 HP and lays down 10-second quarter mile passes, all through a convenient, affordable and expandable, turn-key solution. It represents a threat to the establishment of turbo four cylinder vehicles of yesteryear, and breaks the hearts of muscle cars and exotics everywhere as they are left in the dust by an engine a third the size of theirs, screaming a turbocharged battle cry as it passes. It is a vicious beast, yet a beast easy to tame. It makes for a civilized daily driver that quietly sips premium fuel with surprisingly excellent mileage. Deceivingly quick transient response, with near stock-like turbo lag makes for an experience devoid of the compromises many would expect from an engine this size. It is the answer to the desire for more power, and it’s the brainchild of APR’s talented engineering teams, with over a year and a half of initial development, and a never ending drive for perfection. It is easy to install, blisteringly fast, and produces an absolutely exhilarating driving experience. Welcome to Stage III!

The APR Fueling System is a comprehensive upgrade required to safely support Stage III+ power levels. The upgrade includes a larger in-tank low pressure fuel pump (LPFP) and adds multi-port injection (MPI) to the factory manifold, both of which are ethanol compatible. All necessary hardware is included for a seamless integration and the system is fully controlled by the factory engine control unit (ECU) thanks to APR’s ECU Upgrade.

|Max TQ Gain
|- APR recommends and tuned with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode.|
|- Max increases are based on APR's actual measured stock values and not those reported by VAG. | RON = ROW Fuel Grades | AKI = North American (RON+MON)/2 Fuel Grades.|
|- Reported wheel figures measured using APR's AWD Dynapack dyno with multiple vehicles, using SAE correction and an average of multiple runs for all figures. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications.|
