Only received one of the two filters
I had to return because I only received the cabin filter, not the engine filter. Delivery was delayed and maybe this caused the misplacing of the other part. Not sure. I am placing another order, hoping that it will be complete this time. It is good qualiflty, though.

Buy these, save some $$
Size: size for ASCENT/CROSSTREK/IMPREZA/LEGACY/OUTBACK
Save yourself about $100 by replacing these yourself, we have a Subaru Impreza. Easy to install for a few minutes time spent on YouTube. The dealers make a bundle on this sort of thing.
