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.

Two Filters, Quick and Easy
Size: 16-23 Tacoma, Size: 16-23 Tacoma
The RVgolf Engine+Cabin Air Filters Kit for the Toyota Tacoma V6 comes with two air filters. There is a cabin air filter that fits nicely into the compartment accessed through the glove box and an engine air filter that dropped in easily in the compartment under the hood. Replacement of both filters was easy, didn’t require any tools, and it took more time to empty and replace the items in the glove box than it did to replace both filters. The Toyota dealership quoted me $80 to replace the cabin air filter only. I replaced both filters for less than $30. The filters felt like they were good quality. The engine air filter is multi-layered, with a thin foam layer to keep larger debris from blocking the finer paper filter. The cabin air filter said and looked like it had a carbon layer to absorb smells. The only concern I had was size. After I had replaced both filters I went to slide the engine air filter I replaced into the RVgolf box to throw it away. The engine air filter I replaced would not slide into the RVgolf box. It was too big. After driving for a few days and a couple of hundred miles, I popped the hood and checked the fit of the engine air filter. The fit looked perfect. See attached photos.

Fits 2019 accord (gas engine)
Size: 18-22 Accord
Dealer was going to charge almost $200 to change both of these filters in my 2019 accord. These filters fit perfectly and of same quality as the dealer product. Easy to install, saving me lots of money.
