Performance Gain: 13-18 hp, 12-16 ft-lb (Stock Tune)
Turbo Inlet area increased by up to 160%
Filter surface area increased by up to 40%
Introducing the refined G8X M3 / M4 intake, compatible with the CSL strut brace. Through extensive R&D, we have developed an intake that not only improves the performance of the stock M2/M3/M4 but is also future-proofed to support high-output models exceeding 1000 hp. Completely redesigned from the airbox to the turbo inlets, this system aims to increase flow while reducing pressure drop and keeping intake temperatures low. We utilized the available space to its maximum potential, incorporating two custom-made filters with 40% more surface area than stock. These are used in our patented Venturi housings to smoothly channel air into the turbo inlets. The inlets themselves feature a cross-sectional area up to 160% larger than stock and utilize an advanced dimpled inner surface to reduce friction loss between the airflow and the wall boundary. By creating an air "cushion" along the walls, the air can pass through the inlets at a higher flow rate while reducing pressure loss. This allows the turbos to draw air with less resistance, reducing wastegate duty cycle and improving overall performance.
The Eventuri G8X M2/M3/M4 intake system consists of a number of components engineered to perform a specific purpose and manufactured to the highest standards. We use 100% pre-preg carbon fiber with no fiberglass, ensuring a smooth internal surface to maintain smoother airflow.
Each intake system includes:
- 2 x Patented Carbon Fiber Venturi Filter Housings
- 2 x Bespoke High-Flow Dry Cone Filters
- 2 x Carbon Fiber Intake Ducts
- Carbon Fiber Intake Tube
- 2 x Thermoplastic Turbo Inlets
- Laser-cut Stainless Steel Brackets
- Custom Flexible Hoses
- CNC-machined Bracket Mounts and Reinforcement Rings
- Fits G87 M2, G80 / G81 M3, G82 / G83 M4
- V1 SKU: EVE-G8XM-CF-INT
Before Ordering
〇 Regarding Import Consumption Tax
At Shafutoya Shopping Site, we cover the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.
〇Compatibility Check
All of our product databases are based on North American vehicles (USDM). Please confirm whether the part can be installed on a Japanese vehicle (JDM) before placing your order. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to investigate for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the model year, manufacturer, and vehicle model in the tabs on our homepage, this does not necessarily mean they are compatible with Japanese market 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 Shipping
Shipping costs are paid at the time of checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may rarely differ significantly from the automated calculation. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping within Japan, international shipping takes about 7 to 14 days, so please allow sufficient time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. All products are transported via air freight. They are not shipped via sea freight.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
Generally, all products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents or similar paperwork for these systems. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product. We will only provide returns, refunds, or replacement exchanges for damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Please understand that for products sold through us, warranty-related support will be provided "exclusively through us." We do not provide support through other companies or distributors located within Japan.
