WHAT!?!?! You're crazy to spend $1000 for a 9horse gain in a new car...most new cars will take a high flow air cleaner that will add between 10 and 15 horses and in most applications this add-on only costs 300-400 dollars at top end. And, yes , that's for some of the newer high performance vehicles. So to spend $1000 for a 9horse gain is crazy... If you're payin that... you're payin too much.
