i LOVE my kkm filter...it sounds awesome,and it totally blows away the k+n cone that was on the car when i bought it(although the k+n was all torn up from some genius using bolts that were too long)the holes wouldn't have hurt the k+n's performance,i just didn't want dirt in the engine,so that's why i got the kkm..it totally pulls harder with the kkm than it did with the k+n...also the adapter and filter are both very high quality...i'm going to build or buy a heat shield(i'm not having problems,just think i might have even better performance with the shield)you won't be disappointed with the kkm,or at least i wasn't..
