Eventuri Black Carbon Intake System for A90 / A91 Toyota GR Supra and G29 BMW Z4 [EVE-G29Z4-B48-INT]

Eventuri Black Carbon Intake System for A90 / A91 Toyota GR Supra and G29 BMW Z4 [EVE-G29Z4-B48-INT]

Eventuri’s B48 intake is engineered to deliver a less restrictive path to the turbo while preserving low inlet temperatures. Recognizing the proximity of the OEM system to the exhaust manifold, a major source of heat soak Eventuri employs a fully sealed air box to keep IATs down, then overcomes the stock single-feed limitation by adding a secondary duct that draws fresh air from the wheel-arch opening. The sealed air box integrates a gold-reflective heat shield to minimize radiative heat from the manifold and is maximized for volume with a recess to accommodate potential strut braces. Replacing the stock convoluted tube, a smooth carbon intake tube with a 111mm starting ID tapers precisely to the turbo for an uninterrupted flow path. A custom, high-flow, dry filter, ISO-tested for filtration performance provides a larger filtration area than stock to support consistent, efficient airflow.

Dual Feed Carbon Fiber Air box

• Eventuri crafts the air box from pre-preg carbon fiber to achieve two objectives: fully seal the filter from engine-bay heat and deliver a dual cold-air feed. Positioned beside the exhaust manifold, the filter is encapsulated within a high-volume enclosure; a laser-cut plate with a rubber sealing strip interfaces the intake tube, preventing hot air ingress as the tube passes through. To further curb heat soak, an additional shield with a gold-reflective layer lines the manifold side, reducing radiant transfer. Because a sealed airbag can restrict fresh-air supply, Eventuri augments the stock front-bumper duct with a second feed drawn from the gap between the wheel arch and chassis. A rearward scoop extends into the arch, visible behind the front wheel after installation and an internal splash guard diverts water away from the filter. For race applications using the optional headlamp duct, a removable side panel provides a direct, third cold-air path to the filter for maximum flow.

Carbon Inlet Tube

• The OEM inlet tube uses a flexible, convoluted section to accommodate engine movement, but its multiple faces can induce turbulence. Eventuri replaces it with a smooth, larger-volume carbon tube, maximizing diameter to 109mm at the filter end versus the OEM’s 80.8mm an 82% increase in cross-sectional area. The profile then tapers progressively to the stock turbo inlet to preserve laminar flow. CNC-machined provisions for the temperature sensor and breather adapter ensure precise, OE-quality integration.

Bespoke Cone Filter

• Eventuri’s cone filter uses a double-layer non-woven mesh medium that is ISO-tested to meet OEM-level filtration standards. Built on a heat-stable urethane base, the cleanable element integrates an internal flow-guiding cone to promote convergence and prevent a central stagnation zone. Compared with the stock panel filter, the media offers a substantially larger effective surface area for sustained airflow.

About Eventuri

Eventuri was founded by a team of engineers and enthusiasts with a background in Aeronautics and tuning – all sharing a passion for cars and performance. After owning various intakes over many years for their own cars and being disappointed with the gains which seldom lived up to their claims – they decided to take things into our own hands and rewrite the book. To set a new benchmark in intake design and technology, above all – to engineer systems which provide real gains and then to publish genuine figures. Their systems are extensively developed using cutting edge design, testing and prototyping methods. With a focus on performance, each design undergoes CFD analysis and is then validated at the prototype stage through volumetric airflow, intake temperature and extensive dynamometer testing. They strive to publish all the development information to illustrate the depths they go to in bringing an intake from concept to reality. Only the best materials are selected for each component – even down to the choice of fasteners and fixings in order to ensure that the quality of the end product is second to none. After many years of disappointment with the usual aftermarket intakes, they are proud to be raising the bar and creating intake systems which are setting a new standard and genuinely improve the performance of your vehicle.
