Diffusers work in conjunction withÂ
To guide the high-speed airflow coming from under the car, the diffuser redirects the high-speed airflow to transition smoothly into the low-pressure vacuum at the rear. This creates a smoother airflow under the car and improves the performance of other aerodynamic components such as aerodynamic wings.
Before you order
〇 Regarding import consumption tax
At Shaft-ya Shopping Site, we pay the import consumption tax incurred at the time of import on your behalf, so there are no additional charges beyond the total amount you pay at checkout.
〇Confirmation of compatibility
All product databases are based on North American vehicles (USDM), so please check whether they can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure whether a listed product fits 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 by selecting the year, manufacturer, and vehicle model using the tabs on our top page, this 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 delivery
Shipping costs are paid at the time of payment. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. Regarding large items such as body parts, there are rare cases where there is a significant difference between the amount calculated automatically 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 delivery 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 date. Please note that all products are transported by air. 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 do not comply with the "Japanese vehicle inspection system" in any way, and we cannot provide strength study documents or the like for Japanese vehicle inspections. Therefore, all parts are sold for the purpose of "use on circuits, private land, and off-road," and installation and use are at your own risk.
○ Regarding warranty
Please check the contents of your order as soon as it arrives. As all products are shipped internationally from outside Japan, there may be delivery damage to the packaging box or the product. Please understand that we will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding products with delivery damage, defective products, or products different from your order. Furthermore, regarding products sold through us, we will only handle warranty-related matters "exclusively through our company." Please note that we do not handle matters through other companies or agents located within Japan.
