2015-2021 WRX 3-Port Boost Control Solenoid (by Cobb Tuning)
The Cobb Tuning 3-Port Boost Control Solenoid (BCS) 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 the boost fluctuations common in factory boost control systems and provides stable, repeatable boost control based on your vehicle's tuning. This stable boost control can be provided not only at factory boost levels but also at the extremely high boost levels associated with high-output builds.
The Cobb Tuning 3-Port BCS features 1/4-inch low-profile barb fittings to keep the unit compact and is nickel-coated for corrosion resistance. Viton spools and seals are used throughout, ensuring long life and lubrication. Dow Corning silicone grease is used, the manual override is sealed with an O-ring, and the wiring harness is sealed to the casing using a waterproof grommet and solenoid. Because the wires are ultrasonically welded to the coil, the device is waterproof and can be safely cleaned. The BCS is rated for operation up to 120 psi.

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
All product databases are based on North American vehicles (USDM). Please confirm compatibility with Japanese vehicles (JDM) before placing your order. (If you are unsure if a listed product fits your vehicle, please feel free to contact us. Our support team will investigate 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 checkout. Shipping estimates are calculated automatically when you enter your shipping address on the checkout page. For large items such as body parts, the automatically calculated shipping cost may occasionally differ significantly from the actual cost. In such cases, we will contact you individually via 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 allow yourself 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 are not shipped by sea.
○ 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 the "Japanese Vehicle Inspection System," and we cannot provide documents such as strength calculation reports for Japanese inspection 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. 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 if you contact us within 7 days of receipt regarding items that arrived with shipping damage, defective products, or items different from your order. Additionally, for products sold through us, all warranty-related support will be handled "exclusively through us." Please note that we do not handle support through other companies or distributors located in Japan.
