The Audi B9 RS4/RS5 Eventuri intake system was developed to maintain low intake temperatures without restricting airflow to the turbo. Because the RS4/RS5 engine bay quickly becomes heat-soaked, a simple open-cone system would improve airflow but result in higher intake temperatures. Therefore, we completely redesigned the intake track from the turbo inlet pipes to the front grille with a highly efficient, sealed system. The restrictive stock airbox and flexible plastic intake pipes have been replaced with a Venturi filter housing and a duct system featuring smooth transitions. Furthermore, by removing the complex stock intake pipes and replacing them with our integrated Venturi housing and solid tubes, we have achieved smoother airflow into the turbo inlet pipes. The result is industry-leading performance gains and aesthetics for this platform.
The Eventuri B9 RS4/RS5 intake system consists of numerous components designed to serve a specific purpose and manufactured to the highest standards. Details and design philosophy for each component are as follows:
Each intake system consists of:
- Carbon fiber Venturi housing with integrated tube
- High-flow Generation 2 filter
- Carbon fiber intake duct
- Carbon fiber front scoop
- Carbon fiber secondary duct
- High-quality silicone hoses and OEM-spec hose clamps
- Laser-cut stainless steel brackets
- CNC-machined mounting stubs
Performance Gains: 11–16 hp, 12–17 ft-lb
Before You Order
〇 About Import Consumption Tax
At the Shafto-ya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Our entire product database is based on North American market (USDM) vehicles; please confirm whether or not parts will fit Japanese (JDM) vehicles before ordering. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our homepage, it does not guarantee that they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically once you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our US warehouse. Unlike domestic Japanese shipping, international shipping takes approximately 7 to 14 days, so please allow yourself enough time when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are fundamentally designed and manufactured outside of Japan. Please understand that they are not compliant with "Japanese vehicle inspection (Shaken) standards," and we cannot provide documents such as structural strength evaluations for Japanese inspections. Therefore, all parts are sold for use on "circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacements for shipping-damaged items, defective products, or items different from those ordered if we are notified within 7 days of receipt. Furthermore, for products sold through our company, warranty support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
