DualPlenum
A revolutionary advance in allowing completely even distribution of airflow to all cylinders
Flanges & Fittings
Precision machined flanges available in aerospace grade 6082-T6 Aluminium or optionally Grade 5 Titanium.
Velocity Stacks
Trumpets made from additively manufacture carbon fibre featuring an expansive umbrella form to improve performance.
S-bend Runners
Tapered S-bend runners channel airflow into the cylinders with increasing velocity and minimal turbulence.
The Quench
Using Bernoulli's Principle, The Quench is a highly optimised compression shape to quickly equalise the distribution of air from the first plenum to each cylinder.
First Plenum Stage
Featuring aggressive expansion from the throttle body, the incoming airflow pressure is raised before being rapidly dropped as air is accelerated into The Quench. This pressure change allows the airflow to be directed evenly to each of the cylinders.
375 Hours of CFD Development
100% Even Flow Distribution
to each cylinder*
Each airbox comes with:
- Highest quality pre impregnated carbon fibre
- CNC machined port machined inlet flange
- CNC MAF standoff
- CNC machined brake booster standoff
-CNC machined throttle body flange. Can be optioned in various sizes.
The carbon runners are bonded to the plenum but can be optioned to come detached from the plenum and mated with a screw-in system to facilitate an ITB system.

Production Timeline
Specification Ordering
Your bespoke carbon intake starts by choosing your completely unique specification from thousands of different options.
CNC Flange Machining
All Flanges & Fittings whether titanium or anodised aluminium are machined entirely in-house on our state-of-the-art, large format CNC using the finest 2 micron tooling.
CNC Fitting Turning
Fittings such as the brake booster and fuel vapour are machined on an ZYZ CNC Lathe.
Vapour Bead Blasting
Using the finest ceramic media for an even, high satin sheen, removing all machine marks and deviations.
Colour Anodising
Chemical Type II aluminium anodising in a wide range of colours and contrasts.
Trumpet Production
Your desired specification of trumpet length is additively produced using advanced Carbon Fibre 3D Printing. The plenum and trumpets are then adhered using ultra-high strength body adhesive.
Prepreg Carbon Lay-up
Production begins on the plenum body and runners where motorsport grade pre-preg carbon fibre is hand laid in-house into our own billet aluminium moulds. This is then pressure cured under extreme vacuum and temperature to form a high strength, lightweight structure.
Finishing
Once cured, the prepreg carbon is carefully hand finished with hours of fine sanding. Once levelled, the surface is professionally spray lacquered using several coats and then satin or tinting pigment is finalised in the last coat.
Shipping
Your unique plenum is serialised, recorded and carefully packaged with an update provided on the shipping timeline.
