    Mishimoto Rockstar Aluminum Coolant Expansion Tank ( Part Number: MMRT-WRX-01ERKST)
    Great product, not so great fit.  2 months ago
    4out of 5stars

    I should have done some more research on this before I purchased it, but it didn’t quite fit my application. I have a FMIC and one of the hose inlets hits the charge pipe in this configuration. The product itself is quality and when I change the charge pipe configuration I will install it. Just beware of how close the current expansion tank is to your setup, because this one is much bigger!
