3 Port Boost Solenoid 08-21 STI and WRX
The Cobb EBCS (Electronic Boost Control Solenoid) part # 715750 is a plug and play solution that provides more boost for your 08-2020 STI or 08-2014 WRX. As boost levels are pushed higher during an ECU tune it’s paramount that your boost control solenoid is able to properly manage those increasing boost levels. The OEM Subaru boost solenoid can support small increases in boost but is very limited and quickly becomes a problem on cars looking to make big power. Don’t get caught trying to use the OEM boost solenoid, with a simple upgrade to a Cobb 3-Port Boost Control Solenoid you can be sure that you won’t have any issue with controlling boost on your Subi. We all know the Sti & WRX are capable of much more power then what Subaru delivers from the factory and the EBCS will help you gain access to that power! The Cobb Tuning BCS will eliminate boost fluctuations inherent in the OEM boost control system, providing stable and repeatable boost control when combined with a Brewed Etune. Take the first step in turning up your boost reliably by getting the Cobb BCS setup on your WRX.

Brewed Staff Eric_Brewed –
Must have part for any 2015+ WRX with a Cobb AP. When using these boost solenoids we are able to fine tune the boost control MUCH more accurately than when using the oem solenoid. More accurate boost control means we are able to make more power throughout the entire RPM range all while putting less strain on the engine.
