If you’re chasing more horsepower from your VQ engine, upgrading to a ported intake manifold and ported plenum is one of the smartest airflow mods you can make. Whether you drive a G35, 350Z, G37, or 370Z, improving your air intake system is critical to unlocking real performance gains. At Initiate Motorsports, we specialize in VQ ported manifolds and plenums designed to help enthusiasts push toward the 300 WHP mark and beyond.
Why Ported Intake Manifolds and Plenums Matter on VQ Engines
From the factory, the VQ intake manifold and plenum are designed for mass production and emissions compliance—not maximum airflow. These restrictions limit how efficiently air enters the engine, directly affecting horsepower and throttle response.
A ported intake manifold removes internal casting imperfections and smooths airflow paths, while a ported plenum increases air volume and improves distribution to each cylinder. Together, these upgrades significantly enhance your air intake efficiency.
Benefits of a Ported Plenum on VQ Platforms
A VQ ported plenum is one of the most popular bolt-on upgrades for G35, 350Z, G37, and 370Z owners.
Key benefits include:
-
Increased horsepower and torque
-
Improved throttle response
-
Better airflow balance across cylinders
-
Stronger mid-range and top-end power
When paired with other supporting mods, a ported plenum plays a major role in pushing your build closer to 300 WHP.
Ported Intake Manifold: The Foundation of Airflow Performance
A ported intake manifold is the backbone of a high-performance VQ air intake system. By optimizing runner shape and removing restrictions, a ported manifold allows the engine to breathe freely at higher RPMs.
Benefits of a VQ ported intake manifold include:
-
Increased airflow velocity
-
Improved combustion efficiency
-
More consistent power delivery
-
Higher peak horsepower potential
This upgrade is especially effective on modified G37 and 370Z platforms chasing naturally aspirated gains.
How Ported Plenums & Manifolds Help Reach 300 WHP
Reaching 300 WHP on a naturally aspirated VQ requires efficient airflow. A ported plenum and ported intake manifold, combined with a cold air intake, high-flow exhaust, and proper tuning, are essential components of a proven recipe.
These airflow upgrades ensure your engine can fully utilize fuel and ignition changes made during tuning, resulting in stronger gains across the entire powerband.
