The Hondata 4 port boost control solenoid is designed for use in high boost applications, but also works well in low boost applications. It is normally closed so that on failure you will run off the waste-gate spring to prevent over-boosting. It uses 1/8th NPT fittings which can be adapted to AN fittings.
If you are upgrading from a 3 port solenoid, the boost control tables will need re-tuning.
