Unlocking VQ35DE Performance: How to Get More Horsepower from Your G35 or 350Z

The VQ35DE is one of Nissan's most iconic engines, powering the Infiniti G35 and Nissan 350Z. Known for its smooth power delivery and reliability, this 3.5L V6 has great aftermarket support, making it a favorite among tuners. But how do you squeeze the most horsepower out of the VQ35DE? Let's break it down.

VQ35DE Ported Plenums and Manifold

One of the best ways to improve airflow and gain horsepower is by upgrading to a VQ35DE ported plenum and ported manifold. These upgrades allow for better air distribution, increased throttle response, and improved power delivery throughout the RPM range.

Benefits of a VQ35DE Ported Plenum

A ported plenum increases the volume of air entering the intake, reducing restrictions and improving combustion efficiency. This results in:

  • Increased horsepower and torque

  • Better throttle response

  • Smoother powerband

  • Improved fuel efficiency

Popular brands like Motordyne, Z1 Motorsports, and NWP Engineering offer high-quality VQ35DE ported plenums that deliver proven performance gains.

VQ35DE Ported Manifold: More Air, More Power

A ported manifold enhances airflow by removing internal restrictions in the factory intake manifold. This upgrade is especially effective when paired with a ported plenum, leading to:

  • More consistent power gains across RPMs

  • Increased horsepower at high revs

  • Enhanced engine response and acceleration

How Much Horsepower Can a Ported Plenum and Manifold Add?

When combined with other bolt-ons like a cold air intake and high-flow exhaust, a VQ35DE ported plenum and ported manifold can add anywhere from 10-20 HP, depending on tuning and supporting mods.

Tuning for Maximum Gains

To fully optimize the benefits of a VQ35DE ported plenum and ported manifold, an ECU tune is highly recommended. This ensures the engine adapts to the increased airflow, maximizing performance and efficiency.

Final Thoughts

If you're looking for a cost-effective way to increase horsepower on your G35 or 350Z, investing in a VQ35DE ported plenum and ported manifold is a no-brainer. These upgrades improve airflow, throttle response, and overall engine performance, making them essential for any serious VQ35DE build.
