you simply wouldnt have enough money to get a good one and still get the rest of the things listed and the horsepower gains arent worth the extra 100 bucks. the cold air intake just routes closer to the ground where all the cold air is, the disadvantage to that is that it can soak up water easy and that leads to hydrolock(engine is usless after this). and again the throttle body(BBK, skunk2 etc.) and ECUs wont fall into your budget quidelines.
