Can someone tell me what the difference between the S4 and S5 ACV? I have an ACV, but I do not know which one it is. There is no part number on it. Any help would be appreciated.

they are similar, i think the s5 one is simpler?



ok i just looked. the key difference is that theres a hose nipple sticking out the side of the acv, thats where it gets the air to open the 6ports/vdi from.



looks like you could just cap it off
