STI 08-18 | HPF STAGE 4 | 300KW

The Subaru WRX MY09-14 Stage 4 upgrade starts with our trained technician fitting a cold air intake and high flow air filter, a Blouch Dominator 1.5XT-R turbocharger, Process West top mount intercooler along with a COBB silicone intake pipe and 3 port boost control solenoid. We then increase fuel supply by fitting a high capacity fuel pump and ID1050X fuel injectors. Finally we complete the package by fitting a stainless steel 3" turbo back exhaust system. We then tune your vehicle's ECU on the dyno in real time utilizing the latest Subaru ECU tuning software to maximize power, torque and fuel efficiency.

We complete the upgrade process by testing your vehicle on the road to make final adjustments, optimizing your vehicle's performance and driveability. At the end of this upgrade we will provide you with a dyno graph comparing the before and after power & torque increase the HPF upgrade has made to your vehicle.
