Check if your Subaru has / needs a plastic tray
Size: 72880-FL00A
Works great for my 2015 Subaru Outback, not so much for my 2013 Impreza in terms of installation, missing plastic holder for 2013 Subaru Impreza, while 2015 outback does not require the plastic holder

DIY, super easy to replace.
Fit 2018 crv. I like to change out my air filters before taking my car to the dealership for an oil change. Saves a ton of money to DIY. Easy to do perfect fit.
