Our 4.0TFSI V8 EA825 intake features a completely redesigned and optimized air intake track. Every component, including the lid, has been developed to allow the V8 twin-turbo to draw in air with less resistance, achieving industry-leading performance gains. The factory airbox lid itself limits the size of the flow collector that directs air from the filter to the intake. Therefore, by increasing the height of the center of the lid, we have enabled the use of a larger flow collector and a larger cone filter. This removes the inherent restrictions, setting our product apart from competitors who use the stock lid, which limits the size of both the collector and the filter media. The turbo intakes have a cross-sectional area up to 43% larger than the factory parts, and their advanced dimpled internal structure reduces friction loss between the airflow and the wall boundaries. By creating an "air cushion" against the walls, air can pass through the inlets at higher flow rates with reduced pressure loss. This allows the turbochargers to draw in air with less resistance, reducing the wastegate duty cycle and improving overall performance.
*Measured gains may vary depending on the ECU tune.
The Eventuri 4.0TFSI V8 intake system consists of numerous components designed for specific purposes and manufactured to the highest standards. We use 100% pre-preg carbon fiber, avoiding any fiberglass, to achieve a smooth internal surface that maintains smoother airflow.
Each intake system includes:
- Large Carbon Fiber Airbox Lid
- Carbon Fiber Flow Collector
- 2x Thermoplastic Turbo Inlets with dimpled inner surfaces
- 2x Bespoke High-Flow Dry Cone Filters
- Custom Flexible Hoses
- CNC-machined Breather Ports and Reinforcement Rings
Before Ordering
〇Regarding Import Duties
At the Shaftoya shopping site, we cover the import duties incurred during customs clearance, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Compatibility Check
Our entire product database is based on North American (USDM) vehicles, so please confirm whether or not the product can be installed on Japanese (JDM) vehicles 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 compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by year, manufacturer, and vehicle model using the tabs on our top page, this does not guarantee that they will fit Japanese models 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 automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our warehouse in the United States. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself enough time when placing your order. If you are in a hurry, please contact us in advance to check the delivery time. All products are transported via air freight; they are not shipped by sea.
○Regarding Japanese Road Legal/Shaken Compliance
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they are not compliant with "Japanese Road Legal (Shaken) standards," and we cannot provide strength calculation documents or similar paperwork for the Japanese Shaken system. Therefore, all parts are sold for "circuit, private property, or off-road use," and installation and usage are at your own risk.
○Regarding Warranty
Please inspect your items immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to the packing boxes or the products themselves. Please understand that we will only handle returns, refunds, or exchanges for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located within Japan.
