At Eucadian Performance, we're proud to offer our Z31 gutted intake plenums - a cost-effective upgrade that can transform your SOHC VG30 or VG33 engine's performance. By removing the internal port chambers, replacing the factory throttle body elbow with a smoother-flowing elbow with a 63mm throttle body flange, and polishing the plenum runners, we're able to increase the plenum volume and improve airflow into the cylinders. This results in significant performance gains such as improved mid and high-RPM performance as well as a peak power increase of 5% or more, for turbo-equipped VG30 or VG33 engines.

One of the best things about our gutted plenums is that they maintain a factory look - you can continue using your factory plenum cover, ensuring that your engine looks as good as it performs. We also made it a priority for factory components to be reinstalled without issue which is why we tap the new elbow vacuum ports to factory specifications.

Included with purchase:

  • 4x Anodized 3/8 NPT plugs
  • 4x M8x1.25 Mounting Hardware
  • 6x M6x1.0 Plenum Cover Hardware
  • 1x 1/8" x 3/16" NPT barb fitting

If you plan to send in a core, please contact us AFTER placing your order. All gutted Z31 plenums are subject to a $50.00 core charge at the time of purchase (included in the listed price) which is REFUNDABLE upon receipt of an intake plenum in good condition, with no physical damage and a clean exterior. *NOTE* In order to issue a core charge refund we must receive a core within 30 days from the original purchase date.

As a preventive measure, we recommend applying an anti-seize compound to the anodized NPT plugs before installation to prevent aluminum galling. This ensures that the plugs can be easily removed in the future if needed.

At Eucadian Performance, we pride ourselves on our commitment to quality and customer satisfaction. If you have any questions about our Z31 gutted intake plenums or any of our other products, please don't hesitate to contact us.
