Save your money and put it in something more useful. Type S's already have better air flow and you won't gain much from your 200-300 dollar purchase. You'll gain most benefit from high-end tires, honestly. The type-s is set up to perform pretty well already. The issues come up when you get into tracking your car in the form of brakes, understeering and body sway. Invest in things to improve these unless you just want to make your engine bay look more like you see on TV.
