2015-2021 Subaru WRX/STI Coolant Overflow Tank by Cobb Tuning
The OEM coolant overflow tank for 2015+ WRX/STI models functions adequately, but the cheap plastic material is unsightly and prone to cracking over time, especially under hard driving or extreme thermal cycling. Furthermore, its shape is bulky and gets in the way when adding an aftermarket front mount intercooler.
The upgraded Cobb Tuning Subaru coolant overflow tank solves these issues without compromise. It is made of welded aluminum with the same 1L capacity as the OEM tank and is anodized both internally and externally. The Cobb Tuning tank offers a much better look under the hood and a very simple relocated mounting solution that works perfectly even on stock vehicles. Its shape is also well-suited for routing piping from an aftermarket front mount intercooler.
It includes a custom Cobb Tuning Delrin cap that is highly heat-resistant and provides an overall clean look. Additionally, the kit comes with silicone adapter hoses and an injection-molded cap for the windshield washer fluid reservoir to achieve a cohesive appearance.
This upgraded Subaru coolant overflow tank is affordable, easy to install, and improves both form and function. While it is a necessary part to have when installing an aftermarket front mount intercooler to make room for charge pipes, it is still a no-brainer for adding style and convenience to the engine bay of a stock car or at any other stage of vehicle modification.

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
Our entire product database is based on North American vehicles (USDM). Please confirm whether or not a product can be installed on a Japanese vehicle (JDM) before ordering. (Please feel free to contact us if you are unsure whether a listed product is compatible with your vehicle. Our support team will investigate 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, manufacturer, and vehicle model in the tabs on our homepage, 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 Delivery
Shipping fees are paid at the time of settlement. Estimates for shipping fees are automatically calculated when you enter your shipping address on the checkout page. For large items such as body parts, there are rare cases where the automatically calculated shipping fee differs significantly from the actual shipping cost. In such cases, we will contact you individually via email.
Essentially, all products are shipped internationally from our U.S. warehouse. Unlike domestic shipping in Japan, international shipping takes approximately 7 to 14 days, so please allow ample time when ordering. If you are in a hurry, please contact us in advance to confirm the delivery date. All products are transported via air freight. They are not shipped by sea freight.
○ Regarding Compatibility with Japanese Vehicle Inspection (Shaken)
All products we handle are basically designed and manufactured outside of Japan. Please note that they do not comply with the "Japanese Vehicle Inspection System," and we cannot provide strength calculation documents for the purpose of such inspections. Therefore, all parts are sold for the purpose of "circuit, private property, or off-road use," and installation and usage are at your own risk.
○ Regarding Warranty
Please check the contents immediately upon arrival. As all products are shipped internationally from outside Japan, there is a possibility of delivery damage to the packaging or the product. We will only provide returns, refunds, or replacement exchanges if you contact us within 7 days of receipt for items that have delivery damage, are defective, or are different from what was ordered. Please note that for products sold through us, we will provide warranty support "exclusively through us." We do not provide support through other companies or distributors located within Japan.
