Description
Description
The Eventuri Z4 B48 intake system consists of a number of components engineered to perform a specific purpose and fabricated to the highest of standards. Below, you will see the intricate details as they pertain to our intakes. We have utilized A90 Supra visual material due to the similarities to demonstrate the quality that we bring to your performance parts of choice. We use 100% pre-preg carbon fiber with no fibreglass which means we can achieve a smooth internal surface to maintain smoother airflow. Here are the details for each component and the design ethos behind them:
Each intake system consists of:
- Carbon Fiber Airbox with Dual Feeds
- Bespoke High Flow Dry Cone Filter
- Carbon Fiber Inlet Tube with 111mm opening ID
- CNC Machined Temperature Sensor Mount
- CNC Machined Breather adapter
- Heat Shield with Gold Reflective Backing
- Laser Cut Stainless Steel Brackets
- Silicon Coupler with OEM Specification Clamps
Dual Feed Carbon Fiber Airbox
Crafted from Prepreg Carbon Fiber, 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 we designed the airbox to encapsulate the filter and at the same time provide a large internal volume. To seal the intake tube we have designed a laser cut plate with a rubber sealing strip which 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 we 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 we extended a scoop at the back of our design which protrudes into the wheel arch and 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 we also incorporated an internal splash guard to deflect water away from the filter. The animation below shows both feeds and also the internal splash guard.
Our final consideration was for race applications where our optional headlamp duct is used for maximum cold air flow. We incorporated a removeable panel on the side of the airbox facing the headlamp so that when the optional duct is used, this panel can be removed for another direct feed of cold air to 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. We replace this with our carbon tube which is smooth and also has a larger internal volume. Unlike most aftermarket intakes we maximised the size of our intake tube, the OEM inlet tube has an internal diameter of 80.8mm or 3.2” at the filter end. Our tube has an internal diameter of 109mm or 4.3”. This equates to a massive 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 CNC machined fitting for the temperature sensor and the breather adapter.
Bespoke Cone Filter
Our 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 and 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.
