Add-on 12V solenoid Kit. For 2 Stage Boost Controller
If you already own a Boostvalve boost controller kit but would like to add a "valet" mode or a low boost setting to save gas this kit includes the parts you need.
Air flows through one port when solenoid is "off". Energize solenoid (12V), first port closes and second port opens. High Quality Aluminum valve body. Made in USA. Perfect for setting up multistage boost controllers via toggle or RPM activated switch (not supplied). This allows you to use a dash mounted switch to select between a stock boost setting and Boostvalve controlled boost setting.

Note: most cars use 3/16" fittings, if buying for a VW or Nissan 300ZX Please make a note on order at time of purchase so correct 1/4" fittings are shipped.
