I removed this from my 2008 STi last weekend. On Cobb's website it looks like this will fit an GR series Impreza. It works in all respects and has all the screws, fittings, hoses and what not. The stock filter is clean, but could probably be re-oiled. Also included, and what I used, is an afe washable filter. This filter does not use oil and is simply washed in mild soap and water. The install is pretty trivial, if you pick it up on a warm day I might even help with the install. Only reason for selling is I got tired of the BoV sound you get from this sort of filter. A reflash is recommended after installing this filter, so have your tune ready. Asking $260/bo
