Cabin filter Fram or K&N

Can confirm I bought the CF11811 for my 2018 and it was the correct size!

I got a fram-branded cabin air filter in my BRZ because it had activated charcoal and baking soda in it. It was same price of my OEM filter and has a sturdier build, where my OEM filter had a problem getting pinched and folded somewhat in there.

Since I was in the area, and needed to swap out the cabin air filter, I opted for one from K&N. I have upgraded to the B5.5 filter housing so that is why this should work. There is a slight length difference but it does fit.
