Where did you get those emblems on the engine cover?

Forged has a long pre-order list--I doubt they have filled all their orders..

You're best best is injected performance, as I believe they have received more of the Cos plenums than any other vendor. However, expect to pay MSRP. GL!

What emblems?

The engine cover is a Varis CF 350z piece ($$$, but quality of the CF is top notch)

[Ghayes23]

I thought the 3.5 and V6 looked like they were clear or something. Just hadn't seen it before

I really like how the carbon fiber cover matches up with the carbon fiber sides on the cosworth.

Has there been a dyno with this plenum on a Turbonetics car?

I like it, but I cant justify the 1600$ unless it is proven to gain hp.

Thx! Me likes it too. Varis also offers kevlar/carbon ones that have a red or blue hue to them as well. Varis makes some of the best jdm cf pieces imo.

hmmm, that's a good question. I'd like to see some more dyno's of different F/I setups with the Cos.

edit: The Injected Performance review was on a car with the TN kit at 8 psi: ~10 whp peak gain, ~30whp gain at 6600 rpm:

what??? from the earlier posts it said a gain of 17hp??? wtf?

[jonnylaw]

^^there are gains with the Cos compared to the stock plenum (gains are similar to a spacer on N/A). Obviously the spacer will give you much better performance for the money, however.
