GrimmSpeed Boost Control Solenoid for Evo 8/9 (057019)

Upgrade your Mitsubishi Lancer Evolution 8 or 9 with the GrimmSpeed 3-Port Electronic Boost Control Solenoid (EBCS), designed to provide faster spool-up, improved boost response, and more precise boost control. Part number 057019, this unit is specifically engineered for the 2003–2006 Mitsubishi Evo 8/9 and works with the factory ECU when properly tuned.

Unlike the factory boost control system, the GrimmSpeed 3-port solenoid gives the ECU greater control over the wastegate, allowing your tuner to manage boost more accurately across the RPM range. It flows approximately 10% more than competing valves and is designed to react faster, helping the turbo reach target boost more quickly.

Benefits

A great upgrade for Evo 8/9 owners looking for faster boost response, better boost control, and a clean OEM-style installation.
