Eventuri is a patented new type of intake design. It uses a cone filter, but in Eventuri's design, it is inverted and detached from the intake pipe. Since the filter is no longer directly connected to the intake pipe, the filter itself no longer determines the shape of the airflow. This control is managed by the carbon housing, which is designed to guide air into the intake pipe smoothly without any abrupt changes in geometry. In other words, laminar flow is maintained throughout the intake pipe, significantly improving efficiency. Furthermore, the funnel-shaped housing induces the Venturi effect, increasing airflow velocity as the cross-sectional area gradually decreases along the length of the housing. The entire housing functions as a large speed stack. On the street, because airflow is not obstructed by abrupt geometric changes and laminar flow is maintained, you get smoother power delivery, sharper throttle response, and more power overall.
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
Our entire product database is based on North American specification (USDM) vehicles, so please verify whether parts can be installed on Japanese specification (JDM) vehicles 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 look into it for you.)
If you place an order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted after selecting the model year, manufacturer, and vehicle model using the tabs on our top page, it does not necessarily guarantee that 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 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. 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.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to check the delivery date. Note that all products are transported by air; they are never shipped by sea freight.
○Regarding Compliance with Japanese Vehicle Inspections (Shaken)
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we are unable to provide strength inspection documents or similar paperwork for the Japanese vehicle inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private land, or off-road," 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 may be shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or exchanges for shipping-damaged items, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, for products sold through us, warranty support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
