Subaru Coolant Overflow Tank by Perrin Performance

The PERRIN Coolant Overflow Tank adds clearance for aftermarket intercooler piping and is a great compliment to competitive kits that don’t include one. The universal design will work with nearly all coolant systems that have OEM overflow tanks. Our new coolant tank holds more coolant than previous designs and uses the OEM tank cap for a great seal and an OEM look! This keeps the number of parts down to a minimum and makes for a quick install.

The PERRIN Coolant Overflow Tank is protected from the elements by a black textured powder coating that matches all our intake systems, boost tubes, and engine accessories. Besides being specific to all Subarus, the kit includes instructions, several feet of silicone hose, and multiple mounting brackets for allowing you to install the tank virtually anywhere on any car.
