I heard that Cosworth was coming out with some Subaru intakes, so I went to check them out. They looked awfully familiar.

The Cosworth has a different MAF sensor location on this one, but in my experience the K&N sensor location is better. I don't know why they had K&N change it for them. Maybe there was some interference with the Cozzy FMIC or something.
