How To Identify Solenoids

How do I tell which NX solenoids I have?

OK the small ones like the size of a purge are your 063 200 hp solenoids. The icemans normally say Iceman on the sticker.These are the larger solenoids that are .093 orfice.It will support 300 HP.(these come standard in the stage 1 systems)
Next is the Propower.These are normally staped on the bottom propower.They support 500 hP and come standard in the 2 solenoid directports. The orfice size is .125

These are based off the nitrous.The fuel are a little different.Let me know if you need that info.

Ok... I know I had the stage 1 kit... My Nitrous solenoid is a lot bigger then my purge solenoid.
