Technical Notes:
The PRL Motorsports Stage 1 Intake System is a high-value upgrade that offers significant benefits. This kit replaces the corrugated factory inlet hose with a smoother-flowing 4-ply silicone hose and a high-flow air filter. The pleats in the factory hose disrupt airflow, limiting power potential and throttle response.

Before Ordering
〇 Regarding Import Duties and Taxes
At Shaftoya, we cover all import duties and taxes incurred during import. There are no additional charges beyond the total amount paid at checkout.
〇Verification of Compatibility
Our product database is primarily based on North American (USDM) vehicles. Please verify compatibility with your Japanese domestic (JDM) vehicle before placing your order. (If you are unsure whether a product fits your vehicle, please feel free to contact us; our support team will be happy to assist you.)
We cannot accept returns due to incompatibility if you place an order without confirming fitment beforehand.
Please note that even if items are sorted by year, make, and model using the filters on our top page, this does not guarantee a direct, bolt-on fit for Japanese market models.
All product descriptions are translated into Japanese using translation software. Due to potential discrepancies in wording, please contact us before ordering if you have any questions.
○ Regarding Shipping
Shipping costs are paid at checkout. Estimates for shipping can be calculated automatically by entering your destination address on the checkout page. For large items such as body parts, the actual shipping cost may significantly differ 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 to 14 days, so please allow sufficient time for your order to arrive. If you are in a hurry, please contact us in advance to confirm delivery timelines. Please note that all items are shipped via air freight, not sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken)
The products we carry are generally designed and manufactured outside of Japan. Please be aware that they are not compliant with "Japanese Shaken" (vehicle inspection) standards, and we cannot provide strength evaluation reports or other documentation for Japanese inspection purposes. Therefore, all parts are sold for use on circuits, private property, or off-road use only, and any installation or use is at your own risk.
○ Regarding Warranty
Please inspect the contents of your order immediately upon arrival. Since all products are shipped internationally from outside Japan, there is a possibility of shipping damage to the packaging or the product itself. We will only accept returns, refunds, or exchanges for shipping-damaged items, defective products, or incorrect items if you notify us within 7 days of receipt. Please understand that for products sold through us, all warranty support must be handled "solely through us." We do not provide support through other companies or distributors located in Japan.
