Developed through airflow simulation, controlled flow-bench testing, and real-world performance evaluation, the system replaces the factory airbox and inlet connection with a patented pre-preg carbon fiber Venturi housing, oversized dry air filter, enlarged 94 mm silicone turbo inlet hose, and full-width sealed carbon intake duct. The complete assembly is designed to support the airflow requirements of factory and higher-output turbocharger configurations while limiting exposure to heated engine compartment air.\u003c\/p\u003e\n\u003cp\u003eA central development objective was to increase the available airflow capacity without compromising the supply of ambient air to the filter. The factory intake uses a 73 mm inlet tube, while the Eventuri system incorporates a 94 mm diameter connection between the Venturi housing and silicone inlet hose. This increases the nominal cross-sectional area of the inlet passage by approximately 66%, reducing a significant restriction within the original intake arrangement. The silicone hose maintains the enlarged diameter where packaging permits before transitioning toward the factory turbocharger inlet.\u003c\/p\u003e\n\u003cp\u003eAt the center of the system is Eventuri's patented carbon fiber Venturi housing, which surrounds a bespoke reverse-mounted high-flow dry cone filter. The housing progressively reduces in cross-sectional area toward its 94 mm outlet, providing a controlled transition from the filtration element into the turbo inlet hose. This geometry is designed to promote a consistent airflow velocity profile while reducing abrupt internal transitions that can increase intake resistance.\u003c\/p\u003e\n\u003cp\u003eThe bespoke Generation 2 filter has an outer diameter of approximately 192 mm and provides more than 110,000 mm² of filtration surface area. Its dimensions were selected to maximize the available filter area within the engine compartment. Eventuri incorporates internal flow cones into the filter construction to support the Venturi housing geometry, while the dry filtration medium has been evaluated using ISO-based testing procedures. In separate filter testing, the element demonstrated airflow capacity of up to 900 CFM at a pressure differential of 28 inches H2O when tested in a housing with a 4-inch opening.\u003c\/p\u003e\n\u003cp\u003eThe carbon fiber intake duct extends across the front slam panel area and is designed to maximize the internal volume available within the factory packaging space. Rather than relying exclusively on the original air supply openings, Eventuri incorporates an additional inlet positioned above the slam panel and behind the hood shut line. This supplementary opening provides an effective inlet area equivalent to a circular opening greater than 7 inches in diameter, increasing the ambient-air supply available to the filter during periods of high airflow demand.\u003c\/p\u003e\n\u003cp\u003eA flexible rubber sealing edge forms the interface between the carbon duct and Venturi housing. This arrangement helps prevent heated engine compartment air from entering the intake path while accommodating relative movement between the engine-mounted filter housing and the stationary front duct. The result is a sealed ambient-air supply system that retains the additional inlet capacity required for higher-output applications.\u003c\/p\u003e\n\u003cp\u003eEventuri manufactures the primary carbon components from 100% pre-preg carbon fiber without fiberglass reinforcement. This construction provides smooth internal surfaces and allows the housing and duct geometry to be shaped around the available engine compartment space. The complete assembly also incorporates an aluminum inlet cowl, CNC-machined breather adapter, application-specific stainless steel brackets, and a silicone turbo inlet hose designed around the enlarged 94 mm outlet.\u003c\/p\u003e\n\u003cp\u003eControlled flow-bench testing was conducted using a SuperFlow SF-1020 at a pressure differential of 28 inches H2O. In the manufacturer's related Volkswagen Golf R application, the factory intake recorded 455 CFM compared with 783 CFM for the Eventuri system, representing approximately 72% greater maximum airflow capacity. These results demonstrate the airflow potential of the intake architecture under the documented test conditions; they are not presented as a separate vehicle-specific measurement for the Audi S3 or TTS.\u003c\/p\u003e\n\u003cp\u003eIndependent dynamometer testing was also conducted by Regal Autosport using a Volkswagen MK8 Golf R. Testing compared the factory intake with the Eventuri system on the same day, first with the factory calibration and subsequently with a tuning box installed. Eventuri reports gains of approximately 10-13 horsepower and 12-15 Nm on the stock configuration, increasing to approximately 15-20 horsepower and 25-30 Nm with the tuning box. These results provide supporting performance data for the intake design, although actual gains will vary with vehicle application, calibration, and operating conditions.\u003c\/p\u003e\n\u003cp\u003eBy combining a substantially enlarged inlet passage, high-capacity dry filter, patented Venturi housing, and sealed carbon duct with an additional ambient-air supply, the Eventuri system addresses both intake restriction and thermal management. The revised architecture also increases induction sound under acceleration while maintaining an integrated carbon fiber installation within the engine compartment.\u003c\/p\u003e\n\u003cp\u003eProduct Details\u003c\/p\u003e\n\u003cp\u003eEngineered for Audi 8Y S3 and Audi 8S TTS applications\u003cbr\u003eManufacturer part number: EVE-8YS3-CF-INT\u003cbr\u003ePatented Eventuri pre-preg carbon fiber Venturi filter housing\u003cbr\u003e100% pre-preg carbon fiber construction without fiberglass reinforcement\u003cbr\u003eHigh-gloss black carbon fiber finish\u003cbr\u003eReverse-mounted bespoke high-flow Generation 2 dry cone filter\u003cbr\u003eApproximately 192 mm outer filter diameter\u003cbr\u003eMore than 110,000 mm² of filtration surface area\u003cbr\u003e94 mm diameter Venturi housing outlet\u003cbr\u003e94 mm silicone turbo inlet hose replacing the factory 73 mm inlet connection\u003cbr\u003eApproximately 66% greater nominal cross-sectional area at the enlarged inlet connection\u003cbr\u003eFull-width carbon fiber intake duct with maximized internal volume\u003cbr\u003eAdditional ambient-air opening behind the hood shut line, equivalent to a circular inlet greater than 7 inches in diameter\u003cbr\u003eFlexible rubber duct-to-housing seal designed to accommodate engine movement\u003cbr\u003eAluminum inlet cowl for controlled airflow entry\u003cbr\u003eCNC-machined breather adapter\u003cbr\u003eLaser-cut stainless steel mounting brackets\u003cbr\u003eDeveloped for factory and higher-output turbocharger configurations\u003cbr\u003eRelated Golf R flow-bench testing: 455 CFM factory versus 783 CFM Eventuri at 28 inches H2O\u003cbr\u003eRelated Golf R dynamometer testing: manufacturer-reported gains of 10-13 hp stock and 15-20 hp with a tuning box\u003cbr\u003eReplacement filter: One (1) Eventuri Type D2 filter, EVE-W192-FTR\u003c\/p\u003e","brand":"Eventuri","offers":[{"title":"Default Title","offer_id":67800170627185,"sku":"EVE-8YS3-CF-INT","price":1495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1589\/1087\/files\/51921615627_21eb664daf_b_2c7a190c-deb9-43dc-b429-c25126853877.jpg?v=1792691548","url":"https:\/\/structuredmotorsports.com\/products\/eventuri-audi-8y-s3-8s-tts-black-carbon-intake-system","provider":"Structured Motorsports","version":"1.0","type":"link"}
