Christmas came to Z Car Garage today as we finally received a pair of the much-anticipated Cosworth plenums.  The new design was created to maximize air flow and to make sure that it is distributed to each cylinder as efficiently and evenly as possible. For right now they are made to fit the VQ35DE, non Rev-Up and Rev-Up, engines.  I’ve been told that there is no plan to build a system for the VQxxHR engines yet.

The main body is made of cast aluminum with machined gasket surfaces for a quality seal and partially machined runners for improved flow.  As you can see form the pictures there are two carbon fiber end caps, one on each side of the manifold, to direct incoming air into the boldly pronounced air horns which lead down to the cylinder heads.  These carbon caps are extremely thick and look to be able to stand up to the abuse that any boosted VQ engine can put out.  They are a far cry from the thin, and almost flimsy, original caps that we saw at SEMA in 2007, could this redesign be part of the 16 month delivery delay?

We will be fitting the two plenums that we received on to a pair of turbocharged G35’s by next week, one with a stock VQ35 engine and a JWT (Jim Wolf Technologies) twin turbo kit and the other on a fully built engine with an APS twin turbo system.  I will have more photos and installation impressions by early next week as well as dyno numbers as soon as we get them fitted to the cars.  Maybe the ZCG G35 will be getting one as well…..  Have a great weekend!!
