I Agree,i have been running K&N filters since I was pushing up my Renault 5 turbo 20 years ago now and have never had no problems with them,but I do agree that over oiled filters can cause havoc with the MAF sensor on Impreza's and usually that is the problem. You should still contact K&N with your findings,as really for a performance air filter,a brake horsepower lost of that magnitude is not good enough.SJ.
