Universal Billet Idle Air Control Valve
Designed using a GM 4-pin stepper motor, this IACV is easy to set up. It features 6mm mounting holes and added ORB inlet/outlet threads, allowing you to choose between using hose or AN fittings.
Why use a GM 4-pin motor instead of the standard 2-pin?
-
- The 4-pin idle air control valve featured here allows for more precise control of airflow compared to 2-pin valves. With more pins, there are more "steps" per revolution, enabling finer motor control and more precise adjustment of air flow. In contrast, 2-pin stepper valves generally only control basic opening and closing of the valve.
- 4-pin valves are commonly used in modern vehicles that require precise idle speed control.
- Highly tuned engines may require the high control authority of an IACV to maintain a proper idle. This billet universal IACV kit is the solution to that.

Note: To use this IACV, an aftermarket computer that supports a 4-pin stepper valve is required. It will not work with a stock computer.

Before Ordering
〇 Regarding Import Consumption Tax
At the Shafutoya 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Compatibility Check
Our entire product database is based on North American vehicles (USDM), so please verify compatibility with your Japanese vehicle (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 investigate for you.)
If you order without confirming compatibility, we cannot accept returns due to incompatibility.
Please note that even if items are sorted by selecting the year, manufacturer, and model in the tabs on our top page, it 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 settlement. Shipping estimates are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, the actual shipping cost may occasionally differ significantly from the amount calculated automatically. In such cases, we will contact you individually by email.
All products are generally shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes about 7 to 14 days, so please order with enough time to spare. If you are in a hurry, please contact us to confirm delivery dates in advance. All products are transported by air. They are never shipped by sea freight.
○ Regarding Japanese Vehicle Inspection (Shaken) Compatibility
Please note that all products we handle are designed and manufactured outside of Japan. They are not compliant with "Japanese vehicle inspection standards," and we cannot provide strength calculation documents for such purposes. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off-road," and installation and use are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival of the product. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packaging or the product itself. 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. Additionally, for products sold through our company, all warranty-related support will be handled "exclusively through us." Please note that we do not provide support through other companies or distributors located in Japan.
