Eucadian Performance is proud to present our Kingfisher intake plenum for the Z31 platform. A premium upgrade over our gutted plenum offering, designed to transform your SOHC VG30 or VG33 engine's performance and aesthetic appeal.
A complete reinvention of the factory Z31 plenum, the Kingfisher utilizes 0.125” (3mm) sheet to form the plenum body, CNC billet 6061 intake flange, and billet plenum top. This combination creates a plenum that weighs less than our gutted plenum offering.
The CNC-machined billet intake flange provides tighter dimensional control at the runner inlets, improving airflow transition quality. A 63mm throttle-body flange paired with a larger inlet elbow allows for smoother flow into the plenum.
Billet idle-control flanges are incorporated to ensure factory drivability, idle, and cold-start performance.
A bolt-on plenum that preserves OEM features:
- Maintains factory plenum cover mounting
- PCV port tapped to factory specification (1/4-19BSPT)
- OEM mounting to maintain bolt-on characteristics
- Vacuum Ports: (2x) 1/8" NPT; (2x) 1/4" NPT
Included With Purchase:
- M6x1.0 Plenum Cover Bolts (6x)
- M8x1.25 Plenum Mounting Bolts (5x)
- 3/8" NPT Plugs (4x)
As a preventive measure, we recommend applying an anti-seize compound to the NPT plugs before installation to prevent aluminum galling. This ensures that the plugs can be easily removed in the future if needed.
Note: Pictured with a customer supplied 70mm throttle body. Throttle Body NOT included.
