Kinetix Racing Intake Plenum – Nissan 350Z Infiniti G35

The Nissan 350Z and Infiniti G35 models are already excellent sports cars, but a simple upgrade will help add horsepower with just a few bolts.

The Kinetix Racing Intake Plenum is made to replace the upper half of the factory intake manifold. It adds volume to the front and middle cylinders by effectively eliminating an aggressive angle in the stock plenum that caps off the front cylinders. That means in addition to adding extra air, it equalizes the flow in each cylinder, and you know what they say about things that are firing on all cylinders.

It offers a weight reduction of about 3 pounds, and it installs easily at all the factory mounting points. It will even allow the use of the factory strut bar and engine cover. It’s a fantastic upgrade by itself, but when paired with high-flow catalytic converters, it offers even more horsepower gains. Discover the difference this Kinetix intake manifold will make for your coupe. The increase air flow and performance gains will leave you breathless.

Perfect fit

Item arrived fast. Installed and fit perfectly on my 06 350z. 06 350z owners beware. It does rub on the hood in one very tiny spot. Its not on the Plenum its self. It rubs on the logo design that pops up a little bit. This is due to the lower Plenum collector of the RevUp motor sitting slighter taller than non RevUp's. Its not a big deal at all even emailed Kintetix directly and confirmed it can be still be used. Hood still closed perfectly. Plan on upgrading my hood to the HR hood anyway for the extra clearance as it is a direct bolt on. No vibration. Great for heatsoak as it barely gets warm. Opens up the engine. Great piece.

A Definite Increase in MPG

This was an easy install and took just over an hour to install, it includes very good instructions. After driving for about a week after the install I took a 450 mile trip. I checked my fuel economy and my stock 2004 Nissan 350z went from 21.7 mpg up to 26.3 mpg on the highway. There is also a noticeable increase in low end torque.
