any good?

 

its supposed to be used with nitrous.

 

how exactly does it work?

 

it kills 2 birds with one stone. first off, you dont have to drill and tap your intake for a nitrous nozzle. 2nd, the force with which the nitrous is sprayed into the intake is supposed to cause a suction effect and pull more air through the filter. zex claims like a 25cfm increase with a 50 shot

 

thanks for the info seems like its worth it if you have the nos set up
