Performance increase: 12-20 HP, 8-19 foot-pounds
The Lotus Emira Eventuri system uses our patented carbon fibre housings with our bespoke Gen filters 2, which provide an aerodynamically efficient airflow path from the filter to the compressor. Not just another conical filter with a heat shield, but a unique design that mimics the Venturi effect and maintains laminar flow conditions to reduce drag on the compressor.

The Lotus Emira Eventuri system uses our patented carbon fibre housings with our bespoke Gen filters 2, which provide an aerodynamically efficient airflow path from the filter to the compressor. Not just another conical filter with a heat shield, but a unique design that mimics the Venturi effect and maintains laminar flow conditions to reduce drag on the compressor.
Introducing our Lotus Emira V6 Supercharged intake. This intake is the result of extensive R&D and testing to improve the flow path of the stock system. Our system is a complete redesign of the stock airbox with the aim of reducing drag on the compressor and keeping inlet temperatures low. Utilising our patented venturi housing, the airflow path is now much more direct and laminar than the cuboid OEM airbox. Our custom EPDM tubing is also much smoother internally than the stock tubing, which has large ridges along the curved section which inherently create turbulence. Our version allows movement where it is needed but then has a smooth curved section all the way to the throttle body. Finally, our duct seals the filter housing and draws cold air from the OEM location to minimize IAT.
Dynamometer Testing
This intake has been independently dynamometer tested by Dream Automotive in the UK. The tests were run back-to-back against the stock airbox and several runs were performed with each setup. The car tested had no carbon filters in the stock airboxes. The dynamometer results show a consistent gain across the entire rpm range, which can be attributed to the supercharger working with less resistance due to the increased efficiency of the intake system. The performance gain translates on the road into greater response at half and full throttle, with the car pulling much more eagerly towards the redline.
The Eventuri Lotus Emira intake system is made up of a series of components designed to perform a specific purpose and manufactured to the highest standards. We use 100% pre-preg carbon fiber with no fiberglass, which means we can achieve a smooth internal surface to maintain smoother airflow. Here are the details for each component and the design ethic behind them:
Each intake system consists of:
FILTER HOUSING ASSEMBLY
The filter housing consists of our custom-built 2nd generation filter, aluminum inlet bonnet and stainless steel bracket. The carbon pod shrouds the reverse mounted filter and smoothly shapes the airflow to the OEM turbo intakes. This changes the flow path from the OEM airbox where the airflow enters the base of the airbox and has to deal with 90 degree angles where stagnant areas will form. Our system is much more direct with the airflow entering the front of the filter housing and moving into the MAF tube section without any abrupt changes in direction. The result is a smoother path from the filter to the compressor and therefore it is able to operate with less resistance.
CUSTOM CONE FILTER
To achieve the highest possible flow rate, we use a filter element to make the most of the available space in the engine bay. The filter media is ISO tested to ensure the filtration is in line with OEM standards and is also dry. The filter is constructed with our signature flow cones to support the Venturi housing principle.
PATENTED TECHNOLOGY
Our patented filter housing features a uniform reduction in cross-sectional area as it wraps around the filter and tapers towards the tube. This geometry is reminiscent of the Venturi effect where the airflow accelerates whilst maintaining laminar conditions. It can be thought of as a large velocity stack - below is a diagram showing how our patented design compares to a typical intake system. Our custom filters assist the airflow as it moves through the housings and allow for a uniform velocity profile as the airflow exits the housings. Further details can be found on the Technology and Filters pages.
CARBON CONDUIT
The filter housing is sealed to our carbon air duct which is located in the OEM cold air feed behind the rear wing. This is an excellent air feed as it is very direct and by sealing the duct to our filter housing we ensure that incoming air temperatures remain kept to a minimum.
EPDM FLEXIBLE HOSE
The final part of the intake system before the throttle body is the EPDM hose. This part allows for engine movement and guides the airflow from the filter housing to the throttle body and is therefore a critical component. The OEM hose has a large convoluted section through its curved portion. This causes turbulence as the airflow must negotiate the curve while simultaneously meeting the ridges. Our design removes the ridges across the curve and places a smaller flexible section in line with the filter housing where the path is straight. This allows adequate flexibility for engine movement without impeding airflow. We also added external ribs to reinforce the hose structure.
HARDWARE WORKED
OEM fitment is maintained through the use of our precision machined components. Our coolant tube mount replicates the factory tube mount and holds it in the correct position. By using Delrin we also protect the tubes from sharp corners and potential damage. Our CNC machined MAF sensor mount ensures it performs to OEM specifications and is held securely.
The complete system assembles to provide an intake that improves on the stock airbox in terms of performance, aesthetics and sound.
