    All metal part, great quality, welds look great. Straight replacement fit for stock plastic part. Great additional for a more robust setup or simply if you want some engine bay bling!

    Great looking, easy install ,more capacity, ships to anywhere 1 year ago
    stuart7s157659
    Bought this item due to my original can leaking. This replacement was easy to install, and has great custom looks any car would enjoy. I highly advise this item if you have a leaking OEM can, or just want to make you car look better. This also has increased capacity for more coolant than the stock OEM can, and this is much more durable.

    This is a very well built unit. The welds are flawless. But I did run into one small problem with install. If you have a Perrin rotate kit it will require you moving one of the two smaller nipples. Then it is just a matter of trimming the hoses a little. Overall I am very impressed you can see in the attached picture where I moved the nipple to. As it comes it occupies the same place as the upper charge pipe

    The cap does need to be muscled down but I liked that aspect. It took me all of ten minutes to remove the old one and install the Moroso. I cut the ends of the hoses and used the old hoses:) Works great, no leaks, simple and appears to be heavy duty.

      It says this won't fit a 2015 sti but I can't see a difference really. Do you offer one that will fit a 2015/16?

        A:  This tank will most likely fit with the ETS FMIC, however we cannot guarantee compatibility because we have not tested them together.

    • Q: Moroso Expansion tank subaru  Lambis4 years ago

      I have a gdb-f Subaru impreza version 9. My car is a Japanese import and i have purchased this exact expansion tank. I noticed that this item will not fit to my car because the one on the bottom hole is not the same of the oem tank.. I do not know if the american models have a different oem expansion tank. Please let me know!! Thanks!

        A:  JDM and USDM expansion tanks should be the same and if you are having fitment issues, then please contact our customer service team.
