The BMW E9X M3 Eventuri intake system is the result of thorough research and optimization, further evolving what is arguably one of the best-designed stock intake systems ever made. The E9X factory airbox system is well-engineered, featuring excellent airflow paths and a cold air supply system. However, a closer look revealed restrictions in the intake tubes connecting the airbox to the intake manifold. By redesigning the tubes while retaining the stock airbox, we have improved the intake efficiency of the V8 engine and achieved a power increase. In addition to the new tube design, we found further restrictions within the intake system itself. To overcome this, we designed a scoop to increase the volume of air flowing through the airbox. This further reduces intake air temperatures and improves the system's performance.
The Eventuri E9X M3 intake system consists of numerous components, each designed to serve a specific purpose and manufactured to the highest standards. Details of each component and the design philosophy behind them are as follows.
Each intake system includes:
- Carbon Kevlar 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 you order
〇 About import consumption tax
At Shaft-ya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges other than the total amount paid at checkout.
〇 Compatibility Check
All product databases are based on North American vehicles (USDM), so please verify whether or not they can be installed on Japanese domestic vehicles (JDM) before placing your order. (If you are unsure whether the listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
We cannot accept returns due to incompatibility if you place an order without confirming compatibility first.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model using 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. As there may be confusing expressions, please contact us before ordering if you have any questions.
○ Regarding delivery
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, the automatically calculated shipping cost may rarely differ significantly from the actual cost. In such cases, we will contact you individually via email.
In principle, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please place your order with enough time. If you are in a hurry, please contact us in advance to confirm the delivery date. Please note that all products are transported by air freight. They are not shipped by sea freight.
○ Regarding Japanese vehicle inspection (Shaken) compliance
The products we handle are basically all designed and manufactured outside of Japan. Please understand that they do not conform to the "Japanese vehicle inspection system," and we are unable to provide strength calculation documents or similar paperwork for this purpose. Therefore, all parts are sold for the purpose of "circuit use, private property, or off-road use," and installation and use are at your own risk.
○ Regarding warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, the packaging box or the product itself may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please note that for products sold through us, warranty support will be provided "only through us." We do not provide support through other companies or distributors located in Japan.
