WRX 09-14 HPF STAGE 4 | 300KW

The Subaru WRX MY09-14 Stage 4 upgrade begins with our skilled technician installing a cold air intake and high flow air filter, a Blouch high flow turbocharger, Process West intercooler / turbo adaptor hose and a Process West top mount intercooler. This is complemented by adding a silicone intake pipe and a 3-port boost control solenoid. To enhance fuel delivery, we install a high-capacity fuel pump and XS1200 fuel injectors. The upgrade package is completed with PSR Turbo headers and a stainless steel 3" turbo back exhaust system. Additionally, a TGV delete kit is fitted before we proceed to tune your vehicle's ECU on the dyno in real-time, leveraging the latest Subaru ECU tuning software to optimize power, torque, and fuel efficiency.

Once the upgrade is installed, we road test the vehicle to make any final adjustments, ensuring peak performance and driveability. Upon completion, you will receive a dyno graph showcasing the increase in power and torque, highlighting the improvements made by the HPF upgrade to your vehicle.
