K&N dropin worth it?
Only reason I ask is I had a wrx before my evo 9 and cobb tunning said the factory filter breaths better for the rex. I was wondering if the same goes for the evo or not?

I didnt notice any power gains, but the dv got louder a bit. Im not saying you wont pick up a couple HP, but you wont feel anything.
To me, Id rather just buy new filters than have to clean and oil ones over and over again.
Plus, when I put the K&N in my car, a few months later I sent my oil in for analysis. It came back saying that my air filtration was poor and was contaminating my engine a bit. Sure enough, I could see some dirt and deposits inside the airbox that were not there before. Also some dirt on the inside rubber part of the filter that should be clean. Never had that problem before the K&N, and hopefully it will go away since I'm back to stock filters.
