Z1 Motorsports VQ37VHR Intake Power Mod Kit consists of a stock intake plenum custom modified and a stock intake manifold that has been CNC ported using Z1's exclusive port profile to produce significant gains in horsepower and torque across the the entire powerband. This plenum fits all models with the VQ37VHR engine, including the 370Z & G37. This upgrade is easy to install, but requires the removal of the upper plenum and fuel rail / injectors and everything can be swapped out in around 2 hours.

In order to maximize the potential of the higher flowing Z1 modified VQ37 intake power kit, we recommend several other basic upgrades (all available here in the Z1 VQ37VHR 400HP Package) 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 VQ37s 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.

 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.

Included with this plenum is a set of new upper to lower plenum bolts. Use ONLY the supplied bolts with your plenum, using the incorrect bolts will result in damage that is not covered by Z1.

For your convenience we offer the option to ship a modified plenum first if you pay a refundable core charge.  Upon the receipt of your core Z1 will inspect and credit you for the return.   While these parts are usually in stock this service can be slightly delayed depending on our core inventory and order volume, if you have questions regarding lead times for these parts please give our parts team a call (770) 838-7777.  If you return a core please pack it carefully.  If we receive it in damaged condition, such as any broken plastic air inlet nipples, no credit will be given.   View our core return form and policy
