The Cobb Tuning Subaru Coolant Overflow Tank for 2015-2021 Subaru WRX / STI

The coolant overflow tank designed for the 2015+ WRX/STI by the original equipment manufacturer (OEM) adequately performs its function but suffers from certain drawbacks. The use of low-cost plastic material not only detracts from its visual appeal but also raises concerns about potential cracking, particularly during aggressive driving and exposure to extreme heat cycles. Furthermore, its bulky design poses challenges, especially when integrating an aftermarket Front Mount Intercooler (FMIC).

Addressing these concerns comprehensively, the COBB Subaru Coolant Overflow Tank provides a superior alternative. Constructed from welded aluminum, it maintains the OEM tank's 1L capacity while featuring internal and external anodizing for enhanced durability. Not only does the COBB tank enhance the aesthetic appeal under the hood, but it also offers a streamlined mounting solution suitable for stock vehicles. Additionally, its redesigned shape facilitates seamless integration with piping from aftermarket FMIC systems.

Enhanced Features and Accessories

The COBB tank comes equipped with a custom Delrin cap, renowned for its exceptional heat resistance and contribution to the overall visual appeal. Furthermore, the kit includes a silicone adapter hose and an injection molded cap for the washer fluid reservoir, ensuring a cohesive appearance.

Affordability, Ease of Installation, and Versatility

This upgraded Subaru coolant overflow tank offers a combination of affordability, ease of installation, and enhanced functionality and aesthetics. While essential for accommodating an aftermarket FMIC by creating space for the charge pipe, it remains a sensible choice for both stock vehicles and any stage of the car's modification journey, enhancing style and convenience within the engine bay.
