The BMW E9X M3 Eventuri intake system is the result of extensive research and optimization, further evolving what is arguably one of the best-designed stock intake systems we have ever seen. The E9X stock airbox system is a very well-designed intake featuring excellent airflow paths and a cold air supply system. However, upon closer inspection, we found constraints in the inlet tubes connecting the airbox to the intake manifold. By redesigning the tubes while keeping the airbox intact, we improved the intake efficiency of the V8 engine and achieved a power increase. In addition to the new tube design, we identified a new constraint in the air supply system. To overcome this, we designed a scoop that increases airflow through the airbox. This further lowers intake temperatures and improves system performance.
The Eventuri E9X M3 intake system is composed of numerous components designed to serve a specific purpose and manufactured to the highest standards. The details of each component and the design philosophy behind them are as follows.
*Some images show the S65 carbon inlet plenum and optional airbox lid installed.
The installation guide can be viewed here.
Each intake system consists of the following:
- Carbon fiber intake tubes
- High-flow urethane cone filter
- Carbon fiber inlet scoop
- CNC-machined breather adapter
- Laser-cut stainless steel debris guard
- Silicone hoses and OEM-spec clamps
Before Ordering
〇 Regarding Import Consumption Tax
At the Shafutoya shopping site, we pay the import consumption tax incurred upon import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
All product databases are based on North American vehicles (USDM), so please confirm whether the product can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate 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 top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at the time of payment. 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 may occasionally be a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow yourself plenty of time when ordering. If you are in a hurry, please contact us in advance to check delivery times. All products are transported via air freight. They are not shipped by sea.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese Vehicle Inspection System" at all, and we cannot provide strength calculation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, and off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents of your order as soon as it arrives. As all products are shipped internationally from outside Japan, there may be shipping damage to packaging boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding damaged products, defective products, or products different from what you ordered. Please note that for products sold through us, we will handle warranty-related matters "exclusively through us." Please note that we do not handle matters through other companies or agents located within Japan.
