Introducing the Eventuri Matte Carbon Fiber Plenum for the E9X M3. Constructed from 100% high-quality prepreg carbon, including the internal trumpets, this plenum replaces the factory plastic version and unleashes the roar of the BMW naturally aspirated V8 engine. Because the trumpet lengths are tuned by BMW for the internal volume, changing them could result in a loss of performance; therefore, we have kept the volume unchanged so as not to compromise the car's power delivery. While there is no performance gain from the carbon plenum, the intake sound it produces takes the M3 driving experience to an entirely new level. The raw V8 roar gives the M3 a CSL-like sound. To fine-tune the sound, we went through numerous iterations, varying the thickness of the carbon. The resulting plenum produces an incredible volume and tone of intake sound.
*Some images show the optional matte carbon intake and airbox lid installed. The M badge and V8 badge are optional.
Each Plenum kit includes:
- Carbon fiber base and lid
- 8x Carbon trumpets to factory specifications
- 8x CNC-machined aluminum flanges
- CNC-machined temperature sensor boss
- CNC-machined breather boss
Before Ordering
〇 Regarding Import Consumption Tax
At Shafto-ya Shopping Site, we cover the import consumption tax incurred at the time of import, so there will be no additional charges beyond the total amount paid at checkout.
〇 Compatibility Confirmation
Our entire product database is based on North American vehicles (USDM), so please verify compatibility with 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 be happy to assist 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 model year, manufacturer, and vehicle model in the tabs on our homepage, it does not necessarily mean 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. Estimates for shipping costs are automatically calculated once 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.
Essentially, 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 order with sufficient time to spare. If you are in a hurry, please contact us in advance to confirm delivery times. All products are shipped via air freight. They are not shipped via sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are basically all designed and manufactured outside of Japan. Please note that they are not compliant with the "Japanese Vehicle Inspection System," and we are unable to 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 land, and off-public roads," and their installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility that the packaging boxes or products may sustain shipping damage. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective products, or products different from your order if you contact us within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not handle matters through other companies or distributors located within Japan.
