for our cars SMIC work better until you get into insane HP numbers. secondly think what your doing by putting a huge metal wall infront of your air intake and radiator. thye might look cool but unless your building a 700hp+ monster u wont get equaled results to upgrated Sidemounts. it's your car and ur money so if u want to save by using a FMIC then go for it. they allways look nice in pictures
