The Z1 Motorsports VQ37VHR Ported Lower Intake Manifold is a stock intake manifold custom modified to produce significant gains in horsepower and torque across the the entire powerband. This is achieved by opening the runners to their largest possible diameter while maintaining their shape for maximum flow. This manifold fits all models with the VQ37VHR engine, including the '09+ 370Z (Z34) & '09+ G37 (V36). This upgrade is fairly simple, but requires the removal of the upper plenum and fuel rail / injectors. Installation time may take up to 2 hours.
While the Z1 Ported Lower Intake Manifold works very well alone, Z1 recommends the use of our Intake Plenum Power Mod for increased efficiency and power. This can be done at the same time for moderate power gains on Naturally Aspirated and Forced Induction engines.
In order to maximize the potential of the higher flowing Z1 Ported VQ37VHR Intake Manifold, we recommend several other basic upgrades as well as custom tuning at Z1 Motorsports. It's best to have your car custom dyno tuned to safely maximize the potential of performance modifications and we at Z1 Motorsports tune more VQ's with the Uprev Osiris software than anyone. However if having your car tuned at Z1 is simply not an option, based on our library of experience, we can provide a map well suited for your specific upgrades through our Mail-in Flash Service.
For your convenience we offer the option to pay a refundable core charge and send your stock intake manifold back after install of the Z1 manifold in order to minimize downtime. If you return a core please pack it carefully. If we receive it in damaged condition, such as any broken mounting points, damaged/stripped threads, or cracks, no credit will be given. View our core return form and policy.
Upon removal of this manifold, new lower gaskets are required. New OEM Nissan HR / VHR gaskets can be purchased using the options below.
Torque Specifications for the lower plenum can be found HERE.
This item is currently produced per-order and not stocked. An average lead time of approximately 3-4 weeks should be expected once core is recieved.
