I think you should put it off indefinitely. Penner’s unrestricted tune increases the rwhp to over 170. In the face of that. enhancement by any filter will be unnoticeable. I’ve heard that the new plenum is more efficient than the old but I’d bet that ripping that plumbing out and putting filters on the throttle bodies would have a significant effect, along with decat-ing and retuning.
