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.
**Special Etune offer: All 3 port EBCS orders will receive a $15 credit to be used towards any of out Etune services.
