APS 370 Horsepower Super Sprint High Output System Specifically designed for the US specification 2.5L model STI

APS Super Sprint High Output System
At last here is a "power-up" installation for the US Specification 2.5L STI that has been designed and engineered as a complete system by one of the world's most experienced companies in the field. 

APS has transformed the Subaru's exciting STI by boosting standard flywheel output to a truly exhilarating 370 Horsepower - whilst retaining the stock turbocharger and fuel system. But that doesn't tell the whole story. Improved throttle response and significantly enhanced mid range torque really transforms the STI into a torque monster with fantastic straight line acceleration and much more driveable than the stock vehicle. 

The highly regarded APS commitment to quality is assurance that reliability has been designed into the system.  

All components supplied have been carefully matched and exceed APS' strict performance and reliability criteria. An exhaustive testing program on APS' engineering vehicles ensures maximum performance. 

Performance is not only measured by quick quarter mile times and high speed. At APS we believe it's as important that you have many years of reliable enjoyment and a car that is always exhilarating to drive.
