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.

Boost solenoid uses 1/8th NPT fittings which allow you to use NPT to AN fittings.

For use with:

S300
K-Pro
FlashPro 2006-11 Civic Si
FlashPro S2000
FlashPro 07/08 TSX
