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 increse 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 vehicles 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 vehicles 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.
Like all HPF upgrade packages the Stage 4 package is modular in that it allows the customer to add to the package minimising the requirement to spend money twice when and if further upgrades are desired. HPF strive to bring you maximum performance with high quality components while still maintaining reliability and driveability.
