MAZDASPEED 3-Port Boost Control Solenoid (BCS)
The COBB Tuning 3-Port Boost Solenoid is an excellent upgrade for modern turbocharged vehicles, allowing for precise boost control in a clean package that is easy to install and tune. Our BCS eliminates boost fluctuations common to the OEM boost control system, providing stable, repeatable boost control necessary for precise tuning and consistent performance. With an operating range of up to 120psi, the COBB Tuning BCS is capable of providing stable boost control not only at stock boost levels, but also at the very high boost levels associated with high-output builds.
The COBB Tuning 3-Port BCS features 1/8" low-profile barb fittings to keep the unit compact and is nickel-plated for corrosion resistance. Optional 1/4" nickel-plated fittings are also available separately. Viton spools and seals are used throughout for longevity and are lubricated with Dow Corning silicone grease. The manual override port is sealed with an O-ring, the wiring harness is sealed to the casing using a waterproof grommet, and the solenoid wires are ultrasonically welded to the coil, making the device waterproof and safe to wash.
COBB Tuning has made the installation of the COBB Tuning 3-Port BCS as easy as possible. It mounts in the factory location and plugs directly into the factory wiring harness, making physical installation and electrical connection as simple as possible. The BCS comes with a custom aluminum mounting bracket, stainless steel hardware, all necessary boost lines to complete the connection, and zip ties to neatly route the boost lines through the engine bay. Installation instructions are clear with photos and illustrations to guide you through the installation process, including wiring instructions for both internal and external wastegate configurations.
The COBB Tuning 3-Port BCS is the ultimate electronic boost control device for modern turbocharged applications, engineered with superior boost control, designed for stable performance and extended service life, and configured for easy installation. Take control of your boost today and access the potential of your turbocharged MAZDASPEED!

Before Ordering
〇 About 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 are no additional charges beyond the total amount paid at checkout.
〇Confirmation of Compatibility
Our entire product database is based on North American vehicles (USDM), so please check the compatibility with Japanese vehicles (JDM) before placing your order. (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 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 items are sorted by selecting the year, manufacturer, and vehicle model in the tabs on our top page, it does not necessarily mean they are compatible with Japanese-spec vehicles without modification.
All products have been translated into Japanese using translation software. There may be confusing expressions, so please contact us before ordering if you have any questions.
○ Regarding Delivery
Shipping costs are paid at the time of settlement. Shipping estimates are calculated automatically when 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 shipping cost. In such cases, we will contact you individually by email.
Essentially, 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 for your order. 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) Compatibility
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 strength evaluation documents or similar paperwork for the Japanese inspection system. Therefore, all parts are sold for the purpose of "use on circuits, private property, or off public roads," and installation and use are at your own risk.
○ Regarding Warranty
Please inspect the contents immediately upon arrival. Since all products are shipped internationally from outside Japan, there may be shipping damage to the packing boxes or products. We will only provide returns, refunds, or replacement products if you contact us within 7 days of receipt regarding products with shipping damage, defective products, or incorrect items. Please understand that for products sold through us, warranty support will be provided "only through us." Please note that we do not handle warranty support through other companies or distributors located in Japan.
