The APR K04 Turbocharger System features many upgrades over the 2.0T's factory equipped IHI turbocharger, making it an excellent upgrade. The integrated turbofold design features a cast stainless steel exhaust manifold and turbine housing, integrated into one single unit. This design aids in turbocharger spool while the stainless steel construction is capable of withstanding higher exhaust gas temperature for longer periods of time than lesser materials, such as cast iron. The CNC-machined, billet aluminum compressor wheel and higher flow exhaust turbine wheel expand the turbo's efficiency range, allowing for higher output across a wider RPM range.

Using 93-octane fuel, the APR K04 Turbocharger System produces an astonishing 344 horsepower and 369 ft-lbs of torque. Unlike the factory turbocharger, power stays strong and doesn't dramatically taper towards the vehicle's new 7,100 RPM redline. Ethanol 'flex fuel' compatible engine variants can take advantage of automatic E85 map blending to acheive up to 374 horsepower and 408 ft-lbs of torque simply by filling the tank! APR's calibration experts have safely maximized the full power potential of the turbocharger unit, while keeping reliability at the forefront of their calibration strategies.
