I just pulled the K&N filter off my (new to me) 2014 ES and replaced it with an OEM filter. It's in perfect shape but needs to be cleaned and re-oiled. If you're not local, free + shipping.
I think they are great for onroad applications, but I tend to find the dustiest and sandiest parts of the west when out exploring on my ADV, so I prioritize particle filtration over anything else.
