Show original supplier description
The Kinetix Racing Velocity Manifold is engineered to replace the stock SSV manifold on Nissan 350Z and Infiniti G35 models, providing enhanced performance for higher power outputs. Its innovative design includes a tapered plenum chamber that generates a Venturi effect, ensuring uniform air distribution to every cylinder. This feature, combined with 12% more plenum chamber volume and 10% shorter intake runners, maximizes flow and contributes to higher horsepower potential. Constructed from stainless steel, the Velocity Manifold offers superior heat management compared to aluminum, conducting significantly less heat and reducing heat soak. Precision TIG welding and mandrel-bent pipes are utilized to guarantee smooth airflow throughout the intake tract. The thicker gauge construction is built to withstand higher boost pressures, with a warranty extending up to 30psi. Users can expect significant performance improvements, including horsepower gains of over 30 HP at 6,800 RPM. The improved airflow also leads to a smoother Air/Fuel curve, reducing the need for extensive tuning and promoting more consistent power delivery. This manifold is specifically designed for 2003-2007 Nissan 350Z and 2003-2007 Infiniti G35 models equipped with single throttle body engines, as well as 2003-2008 Infiniti FX35 models. Installation hardware and gaskets are included. **Please Note:** Orders generally ship 5-7 days after order placement.
