Important Notes:
- No ECU calibration or tuning is required for this intake installation.
Technical Notes:
This kit replaces the factory corrugated inlet hose with a 4-ply silicone hose that offers a cleaner look and improved airflow. The factory hose features a bellows-style pleated design that restricts airflow, thereby limiting engine output and throttle response.

Before You Order
〇 Regarding Import Consumption Tax
At Shaftoya, we cover the import consumption tax incurred during customs clearance, so you will not be charged anything beyond the total amount paid at checkout.
〇 Checking Compatibility
Our entire product database is based on North American (USDM) vehicles. Please verify compatibility with Japanese (JDM) vehicles before placing your order. (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.)
Returns due to incompatibility will not be accepted if you order without confirming fitment first.
Please note that even if items are sorted by year, manufacturer, and model using the tabs on our homepage, it does not guarantee that the product will fit Japanese models without modification.
All product descriptions have been translated into Japanese using translation software. Please contact us before ordering if you have any questions regarding potentially confusing terminology.
○ Regarding Shipping
Shipping costs are paid at checkout. Shipping estimates are calculated automatically once you enter your delivery address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the automated calculation. In such cases, we will contact you individually via email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic Japanese shipping, international delivery takes approximately 7–14 days, so please allow ample time when ordering. If you require expedited delivery, please contact us for a delivery estimate in advance. Please note that all products are transported by air; sea freight is not used.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
The products we handle are fundamentally designed and manufactured outside of Japan. Please be aware that they are not compliant with "Japanese Vehicle Inspection (Shaken) standards," and we cannot provide strength calculation reports or similar documentation for such purposes. Therefore, all parts are sold for "use on circuits, private property, or off-road use only," and installation and usage are at the customer's own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be instances of damage to the packaging or the product itself during transit. We will only provide returns, refunds, or exchanges for products damaged in transit, defective items, or incorrect items if you notify us within 7 days of receipt. Please understand that for products sold through our company, we only provide support regarding warranty issues "directly through us." We do not provide support through other third-party companies or agencies located within Japan.
