Whats the diff. 4g63t and 4g63t cyclone

[90TalonDDH]

Hey all I have a 4g63T cyclone motor can someone tell me what the difference is between that and the standard 4g63T cause I dont know for sure but I think it is just the Intake Manifold but why does mine say cyclone instead of ECI multi

Its just a manifold. You are going to have to rig up a way for the butterflies to open. I dont know much about them and think they are kinda pointless.
