3-Port Electronic Boost Control Solenoid

The GrimmSpeed 3-Port Electronic Boost Control Solenoid (EBCS) is engineered to provide precise and rapid boost control for a range of turbocharged Subaru models, including the 2004-2007 STI, 2006-2007 WRX, 2004-2008 Forester XT, and 2004-2006 Baja XT. This solenoid revolutionizes boost control by offering high-resolution management, allowing tuners to safely achieve rock-solid boost levels and optimize power delivery. It facilitates quicker turbo spool and maintains tight control over boost throughout the RPM range. The unit features a balanced valve design that can withstand pressures up to 120psi while maintaining a response time of 6 milliseconds or less, even under extreme heat. The solenoid itself is manufactured by MAC, a specialist in pneumatic control products, and incorporates proprietary GrimmSpeed features. These include special seals to protect against moisture and high-temperature coils for consistent performance. The nickel-plated fittings are robust and rated for 120psi. The construction materials ensure durability in the demanding engine bay environment. Mounting brackets are laser-cut and black zinc plated for corrosion resistance, featuring integrated PEM nuts. The 1/8" NPT nickel-plated fittings are installed with 120psi thread sealant for a secure and compact connection. Upgrading to this 3-port solenoid requires a professional tune to maximize its benefits and ensure safe operation. Users report significant improvements in spool time, with claims of flowing 10% more than competing products. The plug-and-play nature simplifies installation, often taking as little as 15 minutes. The direct-fit design and robust construction ensure it can withstand the heat and vibration common in high-performance applications.
