    Really nice upgrade it looks nice and gives about 5hp I also upgraded the alternator to help with the low voltage at idle as for HP gains cant say yet havent had the car out yet but Im not expecting anything noticable 5hp is not much but I did remove the air pump and upgraded the TB and EGR mount so overall hoping for a little more power
