Description
The OEM Coolant Overflow Tank for the 2015-2017 WRX/STI does it's job well enough but the cheap plastic material is ugly and will potentially crack over time, especially when driving hard and going through extreme heat cycles. It's shape is also clumsy and obtrusive when adding an aftermarket FMIC.
The upgraded COBB Subaru Coolant Overflow Tank solves these problems without any sacrifices. Constructed of welded aluminum with the same 1L capacity of the OEM tank along with internal and external anodizing. The COBB tank looks much better under the hood while providing a very simple relocated mounting solution that works perfectly fine on a stock car. It's shape is also more conducive to fitting piping from an aftermarket Front Mount Intercooler.
A custom COBB Delrin cap is included which is highly heat resistant and adds to the overall clean look. Plus, the kit comes with a silicone adapter hose and injection molded cap for the washer fluid reservoir, giving a uniform look.
Why?
This upgraded Subaru coolant overflow tank is affordable, easy to install, and improves both form and function. It's a must-own part when installing an aftermarket front mounted intercooler to make room for the charge pipe but it's still a no-brainer for a stock car or at any other point in the cars modification journey to add style and convenience to the engine bay.
This Overflow Tank is included in our Front Mount Intercooler Kits for the 2015-2020 WRX and STI.
