Water/methanol injection is a proven method for effectively lowering intake temperatures in forced-induction (turbocharged or supercharged) gasoline engines and suppressing harmful knocking. This allows racers to reliably increase boost pressure and advance ignition timing without the need for expensive high-octane fuel, resulting in power gains of up to 20%. AEM's water injection kits utilize robust hardware and feature advanced functionality that outperforms other systems in the same price range.


Before You Order

〇 Regarding Import Consumption Tax
At Shaftoya Shopping Site, we pay the import consumption tax incurred upon importation on your behalf, so there are no additional charges beyond the total amount paid at checkout.

〇 Compatibility Check
Our entire product database is based on North American vehicles (USDM). Please confirm compatibility with Japanese domestic vehicles (JDM) before placing your order. (If you are unsure whether the listed product is compatible with 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, it does not necessarily guarantee that they will fit Japanese domestic models 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 payment. Shipping estimates are calculated automatically once you enter your shipping 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.

All products are generally shipped internationally from our US warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow sufficient time for delivery. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported via air freight. They are not shipped by sea.

○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Essentially all products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese Vehicle Inspection (Shaken) System," and we cannot provide strength evaluation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for use on "circuits, private property, and off-road" purposes; 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 shipping damage to the packing boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacement exchanges for items with shipping damage, defective products, or items different from your order if you contact us within 7 days of receipt. Furthermore, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located within Japan.
