    Will It Fit Your Vehicle?

    The Hondata 4 port boost controller precisely directs pressure to the top and bottom of your waste-gate diaphragm. It allows much lower waste-gate spring pressure for better low gear boost control and perfect high gear, high boost control.

  • A 10 lb waste-gate spring will enable 50+ psi of boost
  • Better spool-up and mid range power
  • Better duty cycle control

  • For use with:
  • S300
  • K-Pro
  • FlashPro 2006-11 Civic Si
  • FlashPro S2000
  • FlashPro 07/08 TSX
  • 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.

    Disregard the Install Diagram Pictured

    Hondata boost gauge works very well and is very responsive as well, but the install diagram pictured with it here is incorrect, because it says you

    The Best boost control solenoid EVER!

    So I had the infamous Apexi AVC-R boost controller and couldnt get boost to stabalize at all. After some tuning with the Hondata Boost Control Solenoid boost is steady at 16 psi. The power feels alot stronger now since it doesnt drop down and then go back up over and over. I love this solenoid and wish I had gone with it from the beginning.
