I agree with the post above.... a vehicle is pointless with out good brakes. I would start by getting new calipers, 4 piston calipers would be best. 2nd look into getting some cross drilled rotors. They aren't much more than for looks, but do help with excessive braking. As far as mods, a CAI and exhaust wont add more than 5-10hp. and for the price of around $400+. If you really want to increase your HP, look into turbo charging your car. You can find a bunch of mods and how to's on cardomain.com and other sites. Or a motor swap. Either way, a scoop doesn't do your vehicle much good. except extra air flow into your engine compartment. And since you're not running a turbo or super charger, there's not reason why you need more air in the engine compartment
