This performance air intake system allows more air into your engine compared to the restrictive factory air intake housing. It is engineered, tuned, and dyno-tested at Horsepower levels to produce increased horsepower and torque. Air enters the system through an oversized AEM Dryflow synthetic washable air filter that provides excellent airflow, filtration, and performance. The air intake tube is constructed from mandrel-bent aluminum with a durable gunmetal gray powder-coated finish. A custom-shaped heat shield and lid are included. The tapered cylindrical AEM Dryflow air filter is made from oil-free synthetic filter media and can be used for up to 100,000 miles (approx. 160,934 km) before cleaning is required (depending on driving conditions).


Before Ordering

〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we cover the import consumption tax incurred at the time of import on our end, so you will not be charged any additional fees beyond the total amount paid at checkout.

Checking Compatibility
Our entire product database is based on North American vehicles (USDM), so please verify whether it can be installed on a Japanese vehicle (JDM) before placing your order. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle; 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 using the tabs on our top page, it does not necessarily mean they will fit Japanese model vehicles without modification.
All product descriptions 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 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.

Basically, all products are shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time when placing your order. If you are in a hurry, please contact us in advance to check the delivery time. Please note that all products are transported by air; they are not shipped by sea.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Basically, all products we handle are designed and manufactured outside of Japan. Please understand that they are not compliant with the "Japanese vehicle inspection (Shaken) system," and we cannot provide documents such as strength study reports for Japanese inspection purposes. Therefore, all parts are sold for 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. As all products are shipped internationally from outside Japan, there may be shipping damage to the packing boxes or products. Please understand that for items with shipping damage, defective items, or items different from your order, we will only handle returns, refunds, or exchanges if you contact us within 7 days of receipt. Please note that for products sold through our company, all warranty-related matters will be handled "exclusively through us." We do not coordinate with other companies or distributors based in Japan.
