    Extremely straightforward and simple install. A serious no brainer when thinking of ways to increase cooling capabilities.

    I've had this mod on my JDM STI for more than three months and I have not experienced any leaks or cooling issues. The quality is excellent and fitment is perfect. I strongly recommend getting this mod for your Subaru EJ engine.
