Fitment: RS3 8V Gen 2 and TTRS 8S (including 2019 OPF DWNA versions)
The 8V RS3 Gen 2 and TTRS 8S platforms are widely used for high-output engines. Therefore, we have developed a groundbreaking intake system capable of supporting engines producing over 1,000 horsepower. This Stage 3 intake system was developed to achieve maximum airflow while keeping intake temperatures as low as possible. Each component is designed to provide a smooth and unobstructed intake path to the turbocharger. The inner diameter of the intake tube is 103mm (just over 4 inches), featuring a smooth curve from the filter housing to the turbo inlet. The filter itself is also specially designed for this intake, with a large outer diameter of 210mm (8.3 inches) and a filtration area exceeding 130,000 mm². The patented Venturi housing is designed to make the most of the available space in the RS3 engine bay and achieve laminar flow into the turbo tube. Finally, the duct seals the filter opening to the front slam panel without being restricted by the standard entry feed. By lifting the front part of the duct, an additional 7-inch diameter air intake can be added behind the hood to draw in air. Due to its sealed design, this system achieves a flow rate of 840 CFM at 28 inches H2O while minimizing intake temperatures.
The Eventuri 8V RS3/8S TTRS STAGE 3 intake system consists of numerous components designed to serve a specific purpose and manufactured to the highest standards. Because it uses 100% pre-preg carbon fiber rather than any fiberglass, it achieves a smooth internal surface, allowing for more consistent airflow. Details on each component and the design philosophy behind them are as follows:
Each intake system includes:
- Patented carbon fiber Venturi filter housing with 103mm outlet
- Custom high-flow dry cone filter
- Carbon fiber inlet duct (compatible with stock and APR throttle bodies)
- Carbon fiber tube with 103mm inner diameter
- OPF (DWNA) breather adapter
- Heat shield with gold reflective lining
- Laser-cut stainless steel brackets
- Silicone breather hose
- Silicone hoses and reducers
- Optional:
- Carbon turbo inlet (EVE-TRB8V8S-LHD-NIL)
- RS3 carbon headlight duct (EVE-ST38V8S-CF-HDP)
Performance Gain (RS3 stock turbo): 15–18hp, 19–23ft-lb
Performance Gain (RS3 hybrid turbo): 25–30hp, 20–24ft-lb
Flow Bench Data: Stock intake 530 CFM : Eventuri intake 840 CFM
Before Placing an Order
〇 Regarding Import Consumption Tax
At the Shafutoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Checking Fitment
All product databases are primarily based on North American vehicles (USDM), so please check whether the product can be installed on Japanese domestic vehicles (JDM) before ordering. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to look into it for you.)
If you place an order without confirming fitment, we cannot accept returns due to incompatibility.
Please note that even if you sort products by selecting the year, manufacturer, and vehicle model using the tabs on our top page, this does not guarantee that the product will fit Japanese-spec models without modification.
All products are 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. Estimates for shipping costs are automatically calculated when 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 instances, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping within Japan, international shipping takes about 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 not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese vehicle inspection system," and we cannot provide strength evaluation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "circuit use, private land, or off-road use," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility that packaging boxes or products may sustain shipping damage. We will only provide returns, refunds, or replacements for products with shipping damage, defective goods, or items different from what you ordered if you contact us within 7 days of receipt. Please understand that for products sold through our company, warranty support will be provided "only through us." Please note that we do not coordinate with other companies or agencies located within Japan for such support.
