The diffuser works in conjunction with aerodynamic components such as front diffusers, canards, and side rocker extensions to help generate downforce. As the vehicle is in motion, pushing air at the front of the vehicle creates turbulence behind the vehicle.
This diffuser streamlines the airflow running along the underbody and directs turbulence toward the rear of the vehicle, which also enhances the performance of other aerodynamic parts such as rear spoilers.
Please contact us separately for delivery times and shipping costs for large items such as lip spoilers, fenders, and aero kits.
Before Ordering
〇 Regarding Import Consumption Tax
At 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 Confirmation of Compatibility
All of our product database is based on North American vehicles (USDM). Please confirm whether the item can be installed on a Japanese model (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 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 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 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 be rare cases where the automatically calculated shipping cost differs significantly from the actual cost. In such cases, we will contact you individually by email.
Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping 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 confirm delivery times. All products are transported via air freight. They are not shipped by sea.
○ Regarding Compliance with Japanese Vehicle Inspection (Shaken)
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 study documents or similar for that purpose. 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 check the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be cases of shipping damage to the packaging or the product itself. Please understand that we will only provide returns, refunds, or exchanges for shipping damage, defective products, or incorrect items if notified within 7 days of receipt. Furthermore, for products sold through our company, we will handle warranty-related matters "exclusively through us." Please note that we do not work with other companies or agencies located within Japan for these matters.
