Can some1 please explain to me how does the nitrous "Purge Kit" works.

I am talking about the purge kit that hooks up to the intercooler system. DOES IT COMPLETLY BYPASSESS THE ENGINE and IC PORT ONLY?

Please fill me in ASAP
Thanx

 

If you could also provide some PICS for me of that particular setup will be appreciated.

 

it's an extra cylinoid that lets bad nitrous out.. the ones that have oxidzed already.. you hoock it up to your regular nitrous cylinoide.. it's not that hard.. get the kit and you can figur it out..
