Fit as described
Used to install an inner fender liner. Seem a little more fragile than OEM, but suitable for the intended use and much less expensive.

OEM quality
Size: 5 Quart, Style: 1 Pack
This stuff is supposed to be as good or better than OEM Subaru CVT fluid. It works well so far. And it's definitely a lot cheaper than taking it to a dealership and having a flush and fill done
