Hondata Normally Closed Boost Controller
For use with the s300 and K-Pro, the Hondata normally closed 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 if there is a failure you will run off the wastegate spring instead of over boosting. It uses 1/8th NPT fittings which allow you to use NPT to AN fittings if you wish.
