The Eventuri G2x B58 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Eventuri uses 100% pre-preg carbon fibre with no fibreglass which means a smooth internal surface can be achieved to maintain smoother airflow. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
Carbon Fibre Airbox with Dual Feeds
Bespoke High Flow Dry Cone Filter
Carbon Fibre Inlet Tube with 111mm opening ID
CNC Machined Temperature Sensor Mount
Heat Shield with Gold Reflective Backing
Laser Cut Stainless Steel Brackets
Dual Feed Carbon Fibre Airbox
Crafted from Prepreg Carbon Fibre, the airbox serves 2 objectives - to seal the filter against engine bay heat and to provide a dual cold air feed. Since the airbox is positioned next to the exhaust manifold it is crucial for the filter to be fully sealed, so the airbox is designed to encapsulate the filter and at the same time provide a large internal volume. To seal the intake tube, a laser cut plate with a rubber sealing strip secures to the airbox. The intake tube passes through the plate and the rubber seal ensures heated air does not enter the airbox. To further minimise heat soak, there is an additional heat shield with a gold reflective layer on the exhaust manifold side which effectively combats the radiant heat transfer.
Having a fully sealed airbox results in the problem of having a restriction for the cold air feed. The stock airbox draws air from a single duct which extends to the front bumper area. During development Eventuri identified another area to draw cold air from, which was a gap between the wheel arch and the chassis on which the airbox sits. To utilise this feed, a scoop extends at the back of the design and protrudes into the wheel arch; it can even be seen after installation behind the front wheel. This second feed allows the turbo to draw from a larger area therefore reducing the restriction. Since the scoop extends into the wheel arch area, an internal splash guard is also incorporated to deflect water away from the filter.
Carbon Inlet Tube
The stock inlet tube has a flexible and convoluted section to provide movement with the engine. This however also adds the possibility of turbulence in the flow path as there are multiple faces which can cause eddies. The Eventuri carbon tube replaces this, and is smooth and also has a larger internal volume. Unlike most aftermarket intakes, the Eventuri intake tube is maximised in size: the OEM inlet tube has an internal diameter of 80.8mm or 3.2" at the filter end, while the Eventuri tube has an internal diameter of 109mm or 4.3". This equates to an 82% increase in cross sectional area over stock. The tube smoothly tapers down to the stock turbo inlet to ensure airflow remains as laminar as possible.
The tube also has a CNC machined stainless steel ring to reinforce the clamping area.
Bespoke Cone Filter
The Eventuri cone filter is made from a non-woven mesh material which is double layered and is ISO tested to ensure that filtration is in line with OEM standards. The filter is cleanable and very stable at high temperatures with the base material being Urethane. The filter incorporates an internal flow guiding cone to help aid the airflow to converge while reducing the possibility of a stagnation point in the middle of the filter space. The filter medium has a significantly larger surface volume than the stock panel filter.
