APS has transformed the Subaru's "pocket rocket" WRX by boosting standard flywheel output from 160 kW  to a truly exhilarating 210 kW. But that doesn't tell the whole story. Significantly enhanced mid range torque really transforms the WRX 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's strict performance and reliability criteria. An exhaustive testing program on APS's engineering vehicles ensures maximum performance with total engine reliability. 

APS enhanced WRX's have competed and won many hill climbs, club sprints and road rallies. At APS we have a simple philosophy when it comes to performance. To come first, first you must finish. 

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.
