Need a pulse air system to pass smog, should i take it out afterwards?

[dysfunktion]

So i bought a car and now im tryin to get it to pass smog, fix a lot of stuff already, went in and the guy said i need a pulse air system, my car is a 94 240sx, which needs the pulse air system, but the motor is a 96 stock motor, so i dont think i really need it and i want to know if when i put it in just to pass smog, should i take it out after? or just leave it in? and how will it affect my car? Thanks

you need all the emissions that the year of the motor requires. if the 96 has it, then yes, you will need it. or are you not saying that its a 96? if so, then get all emissions equipment, yes you need the pulse air. afterwards, no its not really important.
