Introducing the E9X M3 Carbon Fiber Plenum from Eventuri. Constructed from 100% high-quality prepreg carbon, including the internal trumpets, this plenum replaces the stock plastic unit to unleash the roar of the BMW naturally aspirated V8 engine. While the carbon plenum does not provide a performance increase, the resulting intake sound elevates the M3 driving experience to an entirely new level. The raw V8 tone provides the M3 with a CSL-like sound. The plenum uses varying carbon thicknesses to fine-tune the acoustics, resulting in incredible intake volume and tonality.
*Some images show the optional carbon intake and airbox lid. The M badge and V8 badge are optional.
Each plenum consists of:
- Carbon fiber base and lid (bonded together prior to shipping)
- 8 x OEM-spec carbon trumpets
- 8 x CNC-machined aluminum flanges
- CNC-machined temperature sensor boss
- CNC-machined breather boss
Before Ordering
〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover 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 Compatibility Confirmation
As our entire product database is based on North American (USDM) vehicles, please confirm compatibility with 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 assist you.)
Please note that if you order without confirming compatibility, we cannot accept returns due to incompatibility.
Additionally, please be aware that even if products are sorted by selecting the year, make, and model on our homepage, it does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions are translated into Japanese using translation software. Due to the possibility of confusing expressions, please contact us if you have any questions before placing your order.
○ 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. In rare cases, there may be a significant discrepancy between the automatically calculated shipping cost for large items such as body parts and the actual cost. In such cases, we will contact you via email individually.
All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient 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; sea freight is not used.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
The products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese vehicle inspection system," and we are unable to provide strength inspection reports or similar documentation for Japanese inspection purposes. Therefore, all parts are sold for "circuit, 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, there is a possibility of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or replacement items for products with shipping damage, defective goods, or incorrect items if notified within 7 days of receipt. Additionally, please be aware that for products sold through us, warranty support is provided "exclusively through us." We do not provide support through other companies or agents based in Japan.
