Perrin EBCS Pro Boost Control Solenoid 2008-2021 STI

The PERRIN Electronic Boost Control Solenoid (EBCS) Pro is designed to control today's high performance turbochargers with its ultra-fast response and bomb-proof design. NO TUNING REQUIRED Proper ECU Tuning is required for the safe operation of the engine with this product. Engine performance and fuel economy will also suffer without tuning.  CUSTOM HIGH PERFORMANCE SOLENOID The custom made solenoid coil and valve are made specific to PERRIN specs. This allows the valve to operate almost two times faster and flow almost 50% more than competitors' designs. The EBCS Pro also works with OEM ECU calibrations and reduces overboost conditions that commonly occur, all without causing CEL (check engine lights).  To fully utilize the EBCS Pro, an ECU recalibration is required. DIRECT PLUG & PLAY Our OEM male connector is specific to all Subaru applications. As for 2015-2018 WRX models, the PERRIN male OEM connector is specific to the 2015-2018 WRX (FA20 DIT). This ensures a properly sealed and solid connection between the EBCS Pro and the ECU. Unlike competitors' product that require additional parts and labor, our unique design saves time and makes for a cleaner and simpler install.  SOLENOID CONSTRUCTION The main valve body of the EBCS Pro is made of corrosion-resistant, nickel-plated brass with proper seals to withstand the temperatures and oils seen in a boost control system. Other features unique to the PERRIN EBCS Pro: - Short piston stroke - Balanced piston, immune to different boost levels - Very few parts - Solenoid isolated from contaminated air - Extremely long life - Operates in vacuum up to 120 psi ANODIZED ALUMINUM MULTI-PORT BODY The body of the EBCS Pro is made of 6061 aluminum so it can easily survive under-hood temperatures. The unique PERRIN configuration allows the EBCS Pro to be ultra-compact and work with multiple boost control system setups (internal and external wastegates). This allows the part to adapt to your ever-changing setups.  NICKEL PLATED CONNECTORS High quality nickel plated brass fittings resist corrosion and will not break. For race professionals the EBCS Pro will also accept AN fittings for the best connection possible. INCLUDES EVERYTHING YOU NEED Every EBCS Pro comes with the proper amount of vacuum hose and the proper fittings and mounting plates for your specific year, make, and model Subaru, making for a quick and easy installation process.
