Eventuri New Design Replacement Air Filter For Intake Systems - Type D2

Refresh or upgrade your compatible Eventuri intake system with the Eventuri Type D2 Replacement Air Filter, featuring Eventuri's bespoke reverse-mounted filter design developed specifically for its carbon fibre intake housings. Rather than using a generic aftermarket cone filter, Eventuri developed its own filtration system to work with the unique airflow characteristics of its reverse-mounted Venturi intake housings. The Type D2 combines a double-layer dry filtration medium with carefully engineered internal and external flow-directing cones, helping air travel smoothly through the filter and into the intake tubing. The filtration medium is ISO 5011 tested, conforming to the same filtration testing standard used for OEM filters, while its dry construction eliminates the need for filter oil and avoids the potential for oil contamination of sensitive MAF sensors. The Type D2 is suitable as a replacement filter for a range of compatible Eventuri intake systems, including applications for BMW G8X M2/M3/M4, Audi S3 8Y, Mercedes-AMG A45/CLA45, Volkswagen Golf GTI/R Mk8, Chevrolet C8 Corvette and Porsche 991 GT3 RS. Key Features Genuine Eventuri replacement air filter Eventuri Type D2 Bespoke design developed specifically for Eventuri intake systems Optimised for reverse-mounted Eventuri carbon housings Double-layer filtration medium Dry filter design – no filter oil required ISO 5011 tested MAF sensor-friendly dry filtration Internal flow-directing cone CNC-machined external flow-directing cone Designed to produce a smooth, high-velocity airflow profile Direct replacement for compatible Eventuri intake filters Suitable for replacing worn or contaminated filters Can upgrade compatible older Eventuri systems using the original filter design Bespoke Eventuri Filter Design Eventuri developed this filter specifically around the requirements of its intake systems rather than adapting a generic cone filter. Many Eventuri systems position the filter in a reverse-mounted configuration inside a carbon fibre housing. This creates different airflow requirements from a conventional open cone intake. To optimise airflow through this arrangement, Eventuri invested in a bespoke filter design incorporating dedicated internal and external flow-directing cones. The objective is not simply to provide sufficient filtration, but to control how air travels through the filtration medium and transitions into the intake tube leading towards the engine. Dual Flow-Directing Cone Design A key feature of the Eventuri Type D2 is its two-cone airflow design. The first is the internal cone, which is positioned to help distribute incoming air across the length of the filtration medium. By encouraging a more even velocity profile through the filter, Eventuri aims to reduce unwanted turbulence and make better use of the available filtration surface. The second is the distinctive CNC-machined external cone. Its profile has been developed to draw airflow towards the centre of the filter before creating a smoother transition into the downstream intake tubing. Together, these two elements are designed to control airflow before, during and immediately after it passes through the filter. Dry ISO 5011-Tested Filtration The Type D2 uses a double-layer non-woven mesh filtration medium which has been tested to ISO 5011. ISO 5011 is an internationally recognised test standard used to assess the performance of air-cleaning equipment for internal combustion engines. Importantly, the Eventuri filtration medium is also dry. Unlike an oiled performance air filter, there is no requirement to apply filter oil to the material. This eliminates the potential for excess filter oil to contaminate a vehicle's MAF sensor on applications that use one. For customers using their Eventuri-equipped vehicle regularly, the Type D2 therefore combines performance-focused airflow development with filtration designed around real engine protection requirements. Optimised Airflow Through Eventuri Carbon Housings Eventuri used airflow modelling and CFD development to optimise the filter for its carbon intake housings. The shape of the internal cone helps distribute incoming air across the filter, while the external cone manages the transition from the filtration medium into the downstream pipe. The resulting design is intended to create a smooth, high-velocity airflow profile at the intake outlet, reducing unnecessary restriction before the air reaches the engine. On turbocharged applications, reducing intake restriction can also help the turbocharger achieve the required airflow with less effort. Eventuri reports reduced wastegate duty cycle with its developed intake systems compared with the corresponding factory setup. Developed & Validated Through Dyno Testing Eventuri didn't rely solely on theoretical airflow modelling when developing its updated filter. The company carried out back-to-back dyno testing of compatible Eventuri intake systems using the previous filter design and the upgraded filter. Eventuri reports additional power and torque with the newer filter design, supporting the improvements observed during its airflow development. The exact change varies depending on the vehicle and complete engine specification, so the Type D2 should not be associated with a single universal horsepower figure. It is also important to note that Eventuri's comparison was between an Eventuri intake with its original filter and the same intake with the upgraded filter, rather than a comparison against the factory airbox. Replacement or Upgrade for Existing Eventuri Intakes The Type D2 isn't only intended as a service replacement for a worn filter. Eventuri introduced its updated bespoke filter design across relevant intake systems from February 2018, while also making the filters available to owners of compatible earlier Eventuri systems. This means the Type D2 can serve two purposes: Replace an existing Type D2 filter when servicing a compatible Eventuri intake Upgrade certain older Eventuri intakes originally supplied with the previous double-cone filter design Compatibility ultimately depends on the specific Eventuri intake system fitted to the vehicle. Compatible Eventuri Intake Systems The Eventuri Type D2 replacement filter is used in compatible intake systems for: Audi S3 8Y BMW G87 M2 – Eventuri intake BMW G80 M3 – Eventuri intake BMW G81 M3 Touring – Eventuri intake BMW G82 M4 – Eventuri intake BMW G83 M4 – Eventuri intake Chevrolet C8 Corvette Mercedes-AMG W177 A45 / A45 S Mercedes-AMG CLA45 / CLA45 S Porsche 991 911 GT3 RS Volkswagen Golf GTI Mk8 Volkswagen Golf R Mk8 Important: BMW G8X M2/M3/M4, Chevrolet C8 Corvette and Porsche 991 GT3 RS applications require TWO filters per vehicle. Please confirm that your specific Eventuri intake uses the Type D2 filter before ordering. BMW G8X M2, M3 & M4 Applications The Type D2 is particularly relevant for owners servicing compatible Eventuri intake systems fitted to the latest S58-powered BMW M cars. Applications include: BMW G87 M2 BMW G80 M3 BMW G81 M3 Touring BMW G82 M4 BMW G83 M4 Convertible These twin-turbocharged S58 applications use two Type D2 filters, so two filters must be ordered for a complete replacement. If you're servicing both sides of your Eventuri G8X intake system, selecting a quantity of two will provide the complete filter set required. How Many Filters Do I Need? The number required depends on the application. ONE Type D2 filter required: Audi S3 8Y Mercedes-AMG W177 A45 / CLA45 Volkswagen Golf GTI / R Mk8 TWO Type D2 filters required: BMW G87 M2 BMW G80/G81 M3 BMW G82/G83 M4 Chevrolet C8 Corvette Porsche 991 911 GT3 RS This product is supplied as one individual filter unless otherwise stated, so please order the appropriate quantity for your intake system.

An Eventuri intake system is developed around the interaction between its filter, carbon housing and downstream intake tube. Replacing the original filter with a generic cone filter may change the airflow characteristics that Eventuri designed into the system. Choosing the genuine Eventuri Type D2 retains: The intended reverse-mounted filter configuration Correct fitment inside compatible Eventuri housings Eventuri's internal airflow cone CNC-machined external flow-directing cone Dry double-layer filtration medium ISO 5011-tested filtration The airflow characteristics developed for the intake For an existing Eventuri intake, the genuine replacement filter is the logical choice when refreshing the filtration system.
