Mishimoto welded auxiliary tank for Subarus

Yah, the tank was great. Has been holding pressure just fine. But can we talk about the Mishimoto air freshener that came with it? The scent is perfect! Just a little citrus that blends but does not cover the odor of a coolant, oil, or power steering leak burning off the manifold. I can still clearly smell my brakes as they heat up on mountain passes. Perfect.

Zack,

Thank you for your 5 Star Review! We are glad to hear that you are satisfied with the Mishimoto Aluminum Coolant Expansion Tank for your Subaru! It is great to know that the tank has been performing well and holding pressure as expected. As for the Mishimoto air freshener that came with it, we are glad you appreciate the scent. Mishimoto aims to provide a pleasant experience not only with their products but also with the little extras they include. The citrus scent that blends well and doesn't overpower other odors is a thoughtful addition. Enjoy the fresh and pleasant atmosphere in your vehicle as you hit those mountain passes!

Regards,

Looks great

Installed on my 2010 FXT and it looks great in my engine bay compared to the **** oem one. Install only took 30 minutes for me. If you’re going for some classy engine dress up, this is a perfect upgrade!

Patrick,

As most know the OEM plastic coolant expansion tank is prone to failure. With 22% more capacity Mishimoto Aluminum Coolant Expansion Tank is designed to last longer and perform better! Not only that it looks amazing in your engine bay too! You wont be disappointed!
