- EVE-C8RS6-CF-INT : Audi C8 RS6/RS7 Intake GLOSS carbon

Each intake system consists of:
- Carbon Fiber Airbox Base
- Carbon Fiber Airbox Lid
- Bespoke BMC Panel Filter
- Enlarged Turbo Inlets with CNC machined reinforcement
- Custom Silicon Hoses with OEM Specification Clamps
- Custom Made Hardware
We have completely redesigned the entire airbox system including the base which the filter sits inside. We have combined the slam panel with the lower airbox and increased the volume of this area to help increase the total flow rate. Furthermore, the base has been designed to allow the filter to sit at a more favourable angle to the turbo inlets. Where the stock airbox has a 90 degrees turn from the filter to the inlets, our airbox has a less abrupt angle and this allows for a smoother flow path.
During development we designed and tested 4 different designs for the lid and test results showed that V2 was the highest performing. This design was optimised with CFD simulations and provides a smooth flow path from the filter to the inlets. Our design has an increased volume in comparison to the stock lid and is more organically shaped with smoother curves as opposed to the stock lid which is very cuboid. Furthermore the openings to the turbo inlets have been significantly increased in size.
The inlets have been increased in size at the airbox side by as much as 85% more than the stock inlets and smoothly taper down to the stock turbos. This increased size significantly reduces the drag in the turbos and therefore allows them to work more efficiently. We have also incorporated CNC machined bushes and rings in the inlets for structural strength. For cars with hybrid turbos, we also have separate inlets available on request to match the different inlet diameters.
BESPOKE BMC FILTER
Our airbox required a bespoke panel filter and for this we collaborated with BMC who have developed their iconic filter specifically for our system. It is a washable 4-layer cotton mesh filter which provides superior filtration while maintaining a low pressure drop.
The complete intake system comes together to provide a superior airbox which allows the turbos to reach target boost levels much sooner and therefore the engine is able to produce more power earlier in the RPM range. When combined with a tune where the boost levels are increased, our airbox provides the required de-restricted flow path for the turbos to achieve elevated boost pressures.
