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


Before Ordering

〇 Regarding Import Consumption Tax
At the Shaftoya shopping site, we pay the import consumption tax incurred at the time of import on your behalf, so there will be no additional charges beyond the total amount paid at checkout.

Checking Compatibility
All product databases are based on North American vehicles (USDM), so please verify whether parts can be installed on Japanese vehicles (JDM) before placing your order. (If you are unsure whether a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to assist 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 product descriptions are 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 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 shipping 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 when ordering. If you are in a hurry, please contact us in advance to confirm delivery times. Note that all products are transported by air; they are not shipped by sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
Basically, all products we handle are designed and manufactured outside of Japan. Please be aware that they are not compliant with the "Japanese vehicle inspection system" (Shaken), and we are unable to provide strength calculation reports or similar documentation for this purpose. Therefore, all parts are sold for use on "circuits, private property, or off-road," and installation and use are at your own risk.

○ Regarding Warranty
Please inspect the contents immediately upon delivery. As all products are shipped internationally from outside Japan, there is a possibility of shipping damage to packaging or products. Please understand that we will only provide returns, refunds, or replacement items for products with shipping damage, defective products, or items different from your order if notified within 7 days of receipt. Furthermore, for products sold through us, warranty support will be handled "exclusively through our company." Please note that we do not provide support through other companies or distributors located within Japan.
