V+ Intake Plenum

This plenum increases the total plenum volume by 20% compared to the stock unit and 12% over previous Kinetix versions, leading to improved flow to all cylinders and a more balanced delivery. Constructed from a versatile plastic, it offers a smooth interior surface, eliminating flow restrictions and reducing overall weight by approximately 3 lbs. The material also provides excellent heat resistance, capable of withstanding up to 500 degrees F, and operates at lower temperatures than aluminum options, helping to mitigate heat soak and lower intake air temperatures. This V+ plenum offers significant performance improvements, with gains of up to 14 rwhp on its own, and up to 20 rwhp when paired with Kinetix high-flow cats. It bolts directly onto your vehicle with no modifications required and retains most factory mounting points, allowing for the use of the factory strut bar and engine cover. Installation hardware and gaskets, including a permanently adhered flange gasket and a new throttle body gasket, are included. The product is designed to handle boosted applications up to 10 psi and comes with a lifetime warranty against manufacturer's defects in the plastic material affecting its ability to create a seal. This intake plenum is compatible with 2003-2005 Nissan 350z and 2003-2007 Infiniti G35 (single throttle body engine models), as well as 2003-2008 Infiniti FX35. Please note that the engine cover may not fit with the G35 or FX35 models. Due to State Emissions Regulations, this product is intended for off-road use only in California. Note that the cork gasket is not covered under the lifetime warranty.
