Also, is it really worth adding a lower spacer/upgrading the plenum also? I noticed the 05+ 350Z's came with an updated lower plenum from factory.

I would think that the angled ones are better because the original problem is that the front slopes down, therefore getting less air to the front cylinders as compared to the rear. the equal ones create more air overall, but the angled ones equalize the air distribution over all (if that made sense haha)....at least this is my understanding. I personally just went with a whole new plenum which also fixed the stock problem and is it's bigger in itself, which I paired up with a bored out TB also to allow more air. Just my .02http://

From the looks of things the Blox would be the way to go as far as spacers are concerned. As long as it's not leaking at all.....a spacer is a spacer IMO. Hell, you could probably lay your stock plenum on a sheet of hardened rubber/plastic....trace around it, cut it out, custom drill your own holes and make one yourself LOL Just do some fine trimming with a razorblade ....now that's the poor mans spacer
