New OEM Upper Intake Manifold for all '09+ 370Z and '08+ G37 models equipped with the VQ37VHR engine.

Manufactured in a lightweight, heat resistant plastic, these upper intake manifolds are great for a stock engine.  However, some forced induction customers have found that by adding the additional stresses of Boost Pressure, that these upper intake manifolds may fail.

NOTE: Plenums for 2009-2011 VHR models are discontinued by Nissan. As per Nissan service files, the supplied part is a revised 2012+ plenum, and fits ALL VHR motors. Vehicles manufactured between 2009-2011 will require the use of replacement plenum hardware, to account for the taller brass inserts in the center of the plenum. This is available for all earlier model VHR's using the options below.

Alternatively, Z1 Motorsports offers ported upper plenums available HERE.
