Does the Eventuri Carbon Turbo Inlet fit any Audi 8Y RS3?

The Eventuri Carbon Turbo Inlet in this configuration fits left-hand-drive, U.S.-market Audi 8Y RS3 models only, and it includes the North American breather hardware those cars require. It is not intended for right-hand-drive or non-U.S. vehicles, so confirm your RS3 is an 8Y LHD U.S. car before ordering.

Which turbo flange should I choose?

Select the flange that matches the turbocharger fitted to your car. Three options are offered: Stock Turbo (EVE-TRB8Y-LHD-STK), TTE700/TTE625 (EVE-TRB8Y-LHD-TTE), and SRM GTX3582 (EVE-TRB8Y-LHD-SRM). An incorrect flange will not mate to the turbo, so verify which turbo your RS3 runs before ordering if you are unsure.

How does the Eventuri turbo inlet improve performance?

It removes the main restriction in the factory inlet by enlarging the internal diameter from 72mm to 103mm at the intake side and from 56.4mm to 74mm at the turbo outlet. Smooth prepreg carbon and a silicone coupler with an integrated thermal spacer cut turbulence and heat soak. On hybrid-turbo cars, Eventuri measures gains of 14-20hp and 30-35ft-lb.

What is the Eventuri Carbon Turbo Inlet made from?

It is made from high-temperature prepreg carbon fiber with a smooth internal surface and optimized curvature. Unlike cast-aluminum OEM elbows, the carbon resists heat conduction into the intake charge and keeps the airflow path clean. The inlet is finished in raw carbon with no clear coat for a motorsport aesthetic, and it ships with CNC-machined flanges, silicone couplers, and stainless clamps.

Can I return this inlet, and is it covered by warranty?

No, this item is not eligible for return, so confirm your fitment and flange choice before ordering. Eventuri designs and hand-assembles the inlet in the UK, and warranty coverage plus damage-in-transit support are provided. Contact Bulletproof Automotive with any fitment or support questions before you buy.

Description

Eventuri Carbon Turbo Inlet for 8Y Audi RS3 (LHD)

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 air box, 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.

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
