At IND, we value style, but we value quality even more. When it comes to engines, we never compromise. That is why we offer the AutoTecknic dry carbon fiber intake air duct. Designed to be installed behind the front grille of the F80 M3 and F82/F83 M4, this duct creates a "ram-air" effect by utilizing the movement of intake air to increase static pressure entering the intake manifold under the hood. This allows for a larger volume of colder air to be drawn in, increasing airflow to the engine and lowering engine temperatures. The properties of carbon fiber allow for an air duct that is not only beautiful in appearance but also incredibly lightweight.
Before Ordering
〇 About Import Consumption Tax
At the Shafutoya shopping site, we pay 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 Checking Compatibility
All product databases are based on North American specification vehicles (USDM), so please check the compatibility with Japanese specification vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will investigate for you.)
If you place an order without confirming compatibility, we cannot accept returns due to non-compatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model via the tabs on our top page, it does not necessarily mean 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 if you have any questions before ordering.
○ Regarding Shipping
Shipping costs are paid at the time of payment. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where there is a significant discrepancy between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic delivery in Japan, international shipping takes about 7 to 14 days, so please allow plenty of time when ordering. If you are in a hurry, please contact us in advance to check the delivery time. Note that all products are transported by air. They are not shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially, all products we handle are designed and manufactured outside of Japan. Please note that they are not adapted to the "Japanese vehicle inspection system" in any way, and we cannot provide strength evaluation 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 of your order immediately upon arrival. Since all products are shipped internationally from outside of Japan, there may be delivery damage to the packaging boxes or the products themselves. Please understand that we will only handle returns, refunds, or replacement exchanges for products with delivery damage, defective products, or incorrect items if you contact us within 7 days of receipt. Please also note that for products sold through us, warranty-related support will be handled "only through us." We do not provide support through other companies or distributors located within Japan.
