Z1 Motorsports VQ35HR 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 VQ35HR engine, including the 350Z & G35. 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 VQ35HR intake power kit, 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 VQs 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. All New OEM Nissan HR Throttle Body, Upper to Lower Plenum, and Plenum to Head gaskets can be purchased using the options.

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
