Well, that is not entirely accurate. They do work... VERY well. The problem is that the material used combined with the stress of the engine vaccum is causing cracks. When the plenum is new (not cracked) it works beautifully. In fact, my plenum which is currently cracked is still running quite well. The only noticible thing wrong is my idle which now is a little rough, but once the rpms get above 2000... it's pristine. I just hope that the V4 will be the LAST version that we have to deal with and it will be functionally and structurally flawless.

Well by the plenums "not working", I meant that the majority of them are not staying intact despite whether they still work or not with a crack.
