If you're running the Snow Performance VC50 and want to take advantage of that additional stage of methanol injection, this is the kit for you.

The VC50 Controller allows you to run multiple stages of injection so if you wanted to run a smaller nozzle post intercooler, and then a larger nozzle right before your throttle body, this kit will enable you to do so. 

NOTE: When running two stages you'll need a dedicated solenoid for the second stage

This image is in the process of being updated. If upgrade is purchased a new low profile nozzle holder will be sent not the nozzle holder in the picture.
