AEM V3 Water/Methanol Injection Kit - Multi-Input (No Tank)

For racers with high-compression naturally aspirated or forced induction engines looking for an alternative to boost-dependent water/methanol injection controllers, AEM’s Multi-Input WMI Controller provides the solution. The multi-input design allows users to install AEM’s water/methanol injection kits on high-compression naturally aspirated (NA) vehicles via MAF/IDC settings, or on ultra-high boost vehicles (over 40 PSI) by utilizing an external MAP sensor. The multi-input controller supports external 0-5v voltage-based MAP sensors, frequency-based injector duty cycle (IDC) inputs, frequency-based mass airflow (MAF), and 0-5v voltage-based MAF. The multi-input controller is available in the following three types of kits: a 1-gallon (approx. 3.79L) tank kit with a single injector for gasoline engines (PN 30-3350), a tankless kit with a single injector (PN 30-3352), and a 5-gallon (approx. 18.9L) tank kit with two injectors for high-performance gasoline applications (PN 30-3351).

Before Placing Your Order

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

〇Compatibility Check
Our entire product database is based on North American vehicles (USDM), so please verify whether parts are compatible with Japanese domestic vehicles (JDM) before ordering. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will be happy to check 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, make, and model in the tabs on our top page, this does not guarantee they will fit Japanese market models without modification.
All product descriptions are translated into Japanese using translation software. If there are any confusing expressions, please contact us before ordering.

○ 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.

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 place your order with sufficient time. If you are in a hurry, please contact us in advance to confirm the delivery date. Note that all products are transported via air freight; we do not use sea freight.

○ Regarding Japanese Vehicle Inspection (Shaken) Compliance
Please be aware that all products we handle are designed and manufactured outside of Japan. They are not compliant with the "Japanese Vehicle Inspection System," and we cannot provide structural strength certificates or similar documentation for this purpose. Therefore, all parts are sold for use on "circuits, private land, or off-road," and any installation and usage are at your own risk.

○ Regarding Warranty
Please check the contents immediately upon arrival. Since all products are shipped internationally from outside of Japan, there may be instances of shipping damage to the packaging or the product itself. Please understand that for products with shipping damage, defective products, or incorrect items, we will only handle returns, refunds, or exchanges if notified within 7 days of receipt. Furthermore, for products sold through us, all warranty-related support will be handled "exclusively through our company." Please note that we cannot provide support through other companies or distributors located within Japan.
