The Z1 Motorsports VQ37VHR Intake Plenum Power Mod is a stock intake plenum custom modified 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 and can be swapped out in around half an hour. 

In order to maximize the potential of the higher flowing Z1 modified VQ37 intake manifold, 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.

The Z1 intake plenum produces more peak power and area under the curve on a Natural Aspirated VQ37VHR than any intake manifold on the market and for a modest price. 

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

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.

Questions our customers have asked...

Hi Jon I need Intake Plenum Power Mod *2pcs. One is VQ37 and another is VQ35HR. May i send two original VQ37 intakes to you,you send VQ35+VQ37 to me ? If you can,how much do i need to pay you ?

Response: Allen, We need cores that match what we are providing to give the full core credit. Any parts that didn't match could only be credited by store credit from the core credit program: (Link) Also you do need the lower that matches the upper you want to use if you are trying to swap this onto the an HR platform.
