Eventuri Carbon Turbo Inlet for 8Y Audi RS3 (LHD) [EVE-TRB8Y-LHD-SRM/EVE-TRB8Y-LHD-TTE/EVE-TRB8Y-LHD-STK]

Eventuri Carbon Turbo Inlet for 8Y Audi RS3 (LHD) [EVE-TRB8Y-LHD-SRM/EVE-TRB8Y-LHD-TTE/EVE-TRB8Y-LHD-STK]

Eventuri’s full carbon RS3 Turbo Inlet Elbow is now available for the 8Y platform. It retains the proven geometry of the original 8V design, with additional fitment hardware tailored to the revised North American 8Y breather system. Developed through months of focused R&D, the inlet is engineered without compromise optimizing volume, flow quality, and temperature for maximum efficiency.

Volume

• Eventuri specifies a 103mm inlet versus the OEM’s 72mm, and a 74mm outlet versus the OEM’s 56.4mm. The substantially larger internal diameters increase overall inlet volume, de-restricting the flow path to the turbo for improved efficiency.

Flow Quality

• Eventuri emphasizes that volume alone is insufficient without a smooth, efficient flow path to the turbo. Constructed from high-temperature prepreg carbon fiber, the inlet features a refined internal surface that contrasts with the rougher interiors typical of cast-aluminum OEM and aftermarket elbows. Combined with the elbow’s carefully managed curvature, this finish minimizes turbulence and promotes stable, high-quality airflow.

Temperature

• Eventuri prioritized minimizing heat conduction into the airstream. Whereas the OEM inlet bolts directly to the turbo conducting heat as it spools, Eventuri’s design interfaces via a machined turbo flange and a silicone coupler with an integrated thermal spacer, isolating the carbon elbow from direct contact. This thermal barrier, combined with carbon fiber’s inherently low through-thickness conductivity, reduces heat transfer to the intake airflow.

Flow Bench Testing

• Eventuri validated performance on a SuperFlow SF-1020, measuring maximum flow at a 28″ H₂O pressure drop. All elbows were tested the same day under controlled conditions using an identical jig. Results highlight the OEM elbow’s restriction: Eventuri’s design increased maximum possible flow rate by 42% with the stock flange and by up to 58% with the larger GTX flange. For RHD applications, a scallop was added to clear the brake fluid reservoir; despite the slight volume reduction, the RHD variant still achieved a 52% increase over stock with the GTX flange.

Dyno Testing

• Eventuri’s carbon elbow has undergone independent validation by respected tuners worldwide. BR Performance Netherlands tested the system on a TTRS fitted with a TTE700 hybrid turbo, conducting same-day, back-to-back runs with the hood closed. Comparisons were made between the stock airbox, Eventuri’s Stage 3 intake paired with the OEM elbow, and the same intake upgraded with Eventuri’s carbon elbow.

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.
