Hondata Boost Control Solenoid
The Hondata Normally Closed boost control solenoid is for high boost applications in the s300, K-Pro and 2006+ Civic Si, 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.
Use this in conjunction with the AJP Si turbo kit when boosting over 11 psi.
It uses 1/8th NPT fittings which allow you to use NPT to AN fittings.
