Subaru 3 Port Boost Control Solenoid (BCS) 2015-2021 WRX



The Cobb 3 port EBCS “electronic boost control solenoid” is one of the first mods we recommend for any WRX or STI. While the factory EBCS works ok at stock boost pressure it is not able to keep up at higher boost pressures. If you are looking to get the most reliable power and boost out of your Subaru the Cobb 3 port EBCS is exactly what you need. Use the EBCS with OTS Cobb calibrations or get the most out of your engine with a customer Pro tune calibration through our Etune services. Works with both internal and external waste gates for stock or aftermarket turbos.
