Acceleration time: 60-130 mph reduced by 0.22 seconds
Max flow rate per airbox (at 28" H2O): 620 CFM for stock intake, 736 CFM for Eventuri intake
The F90 M5 and F9X M8 Eventuri intake systems were developed following extensive testing and airflow simulation analysis. Featuring sealed filter housings, they maintain consistent IATs (Intake Air Temperatures) even while stationary. The combination of shrouds that seal the housings, along with unique scoops and shields, prevents airflow restriction while maintaining low IATs through cold air saturation. The large front air scoops direct ambient air straight into the intake area, preventing engine heat soak. Furthermore, the shields—which feature a gold heat-reflective lining—incorporate flow guides to direct ambient air from the scoops to the filters. We also succeeded in increasing the cross-sectional area of the inlet tubes that draw air from the strut brace openings by over 30% compared to the stock intake. This improves turbocharger performance, reduces intake restriction, and lowers the wastegate duty cycle.
Some photos show the F90 M5 intake system, which is an optional extra.
The Eventuri Difference
The F90 M5 / F9X M8 Eventuri system utilizes patented carbon fiber housings and a second-generation bespoke filter to provide an aerodynamically efficient airflow path from the filter to the turbocharger. This is not merely a cone filter with a heat shield, but a unique design that induces the Venturi effect and maintains laminar flow, thereby reducing turbo restriction.
Each intake system includes:
- 2 x Carbon fiber Venturi housings with integrated tubes
- 2 x Bespoke high-flow second-generation filters
- 2 x Carbon fiber filter shrouds
- 2 x Aluminum inlet cowls
- 2 x Carbon fiber air scoops
- 2 x Laser-cut heat shields lined with gold heat-reflective material
- 2 x Laser-cut air ramps integrated into the heat shields
- High-quality silicone hoses and OEM-specification hose clamps
- Optional: Carbon turbo inlets (Gloss Finish (EVE-F9XM5M8-CHG) or Matte Finish (EVE-F9XM5M8-CFM-CHG)
Before placing your order
〇 Regarding Import Consumption Tax
At the Shafutoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so you will not be charged any additional fees beyond the total amount paid at checkout.
〇Compatibility Check
All product databases are based on North American vehicles (USDM), so please verify compatibility with Japanese vehicles (JDM) before ordering. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle; 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 a product is sorted by selecting the year, manufacturer, and vehicle model via the tabs on our top page, it does not necessarily guarantee a direct fit for Japanese-spec 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. Shipping quotes are calculated automatically when you enter your delivery 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 cost. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international delivery takes approximately 7 to 14 days, so please allow sufficient time when ordering. If you are in a rush, 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 Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with "Japanese vehicle inspection standards," and we cannot provide documents such as strength calculation reports for Japanese inspection purposes. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use," and installation and usage are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside of Japan, there may be instances of damage to packaging boxes or products during transit. We will provide returns, refunds, or replacements for damaged items, defective products, or incorrect orders only if you contact us within 7 days of receipt. Please understand that for products sold through us, warranty support will be handled "exclusively through us." We do not provide support through other companies or distributors located within Japan.
