G35/350Z REV-11 Upgraded Upper Plenum | VQ35DE

The REV-11 Upper Plenum is the best all around upgrade to complement the airflow needs of the VQ35DE engine. Compared to the restrictive OEM version, the REV-11 features a bored out intake entrance and a fully polished inside, eliminating casting marks and turbulence for a smoother airflow path. This allows your engine to breathe freely, translating into sharper throttle response, smoother power delivery, and faster acceleration.

The upper plenum is bored out to increase airflow capacity, creating a larger and more efficient opening for incoming air. The completely polished inside ensures there are no obstructions or rough surfaces to disrupt airflow, reducing resistance and maximizing intake efficiency. With improved airflow comes smoother combustion, enhanced acceleration, and a more responsive driving experience.

To further improve performance, every REV-11 upper plenum is finished with a thermal-resistant ceramic coating. The upper section of the intake manifold is especially prone to heat soak, as heat rises from the lower plenum and transfers through the aluminum body. The ceramic coating acts as a barrier, keeping the plenum cooler and reducing intake air temperatures. Cooler intake temps mean denser air, which directly improves engine performance.
