The Z1 Motorsports VQ35HR NA Power Package includes tested and proven components necessary to maximize the output of your naturally aspirated 350Z or G35.
After over a year of development and extensive dyno testing on multiple cars, we have released an intake manifold modification that complements our mid length exhaust header design which produces more peak power (while maintaining power under the curve) than any other products on the market we've tested including more expensive long tube headers and competitors intake manifold upgrades.
In conjunction with a Z1 Cold Air Intake Kit and a quality high flowing exhaust system the Z1 VQ35HR N/A Power Package can produce 310+ rear wheel horsepower on a DynoJet on 93 octane fuel when properly tuned with Uprev Engine Management. Gains will be even higher on cars equipped with large cams, nitrous, or E85! We have not included the intake, exhaust, or engine management systems in this package because many people have already purchased these items. We recommend installation and tuning through Z1 Motorsports.
This package includes the following components:
A $250 refundable core charge applies to the intake manifold. If the core manifold is received broken or damaged no refund will be given. Pack carefully. View our core return form and policy
