Simplified Wiring
The new wiring harness is terminated with positive-lock connectors at one end, and color-coded wires make installation easy. The harness includes an integrated pump ground circuit to simplify the wiring process and eliminate the possibility of pump malfunctions caused by shorts in the system. A wire is also included for adding an optional on/off solenoid to stop fluid flow when the system is inactive.
Improved Injector Flow and Nozzle Sizes
AEM engineers have thoroughly refined the controller's flow control strategy to achieve more linear flow output. This means that flow delivery is better matched to engine water/methanol injection requirements, further optimizing charge air cooling and knock control. Each kit includes three resized injector nozzles to allow for increased flow capacity (flow charts can be viewed on our website).
New Low Fluid Level Indicator
A more accurate conductive low fluid level sensor is integrated into the tank and features a positive-lock connector that matches the color-coded wires of the wiring harness. This sensor eliminates the potential for false readings caused by debris interference.
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.
〇Confirmation of Compatibility
Since all product databases are based on North American vehicles (USDM), please confirm whether or not parts can be installed on Japanese vehicles (JDM) before ordering. (If you are unsure if a listed product is compatible with your vehicle, please feel free to contact us. Our support team will be happy to check for you.)
If you order without verifying compatibility, we cannot accept returns due to incompatibility.
Please note that even if products are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, this does not necessarily mean they will fit Japanese model vehicles without modification.
All products 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. Estimates for shipping costs are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where there is a significant difference between the automatically calculated shipping cost and the actual shipping cost. In such cases, we will contact you individually via email.
Basically, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please allow plenty of 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 will not be shipped by sea freight.
○ Regarding Compliance with Japanese Vehicle Inspections
Please note that all products we handle are basically designed and manufactured outside of Japan. They are not adapted to the "Japanese Vehicle Inspection System" in any way, and we are unable to provide strength study documents or similar for the Japanese inspection system. Therefore, all parts are sold for use on "circuits, private land, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there may be shipping damage to packaging boxes or the products themselves. Please understand that we will only provide returns, refunds, or replacements for products with shipping damage, defective products, or incorrect items if you contact us within 7 days of receipt. Furthermore, regarding products sold through our company, warranty support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located within Japan.
