I personally have been doing "mods" to cars for ALOT of years. Air intake kits are mostly show, the most anyone could expect from even the most blueprinted Air intake would be 5 - 8 HP. The above being said, there are more signifignt risks to using a cold air kit that is outside of the fender and close to the ground (i.e. Water sucked into the engine).

My advise is to go with the Stillen box and Z tube. They maintain stock look and placement with better overall airflow than your currently getting. The "long" cold air may move the filter to "cooler" air, but it also puts it very close to the ground and risks sucking up water on a heavy rain day or deep puddle and that spells disaster. Some may argue that some kits are designed to cause the water to be expelled along the route to the throttle body, but I am not going to risk my engine and an arguable 3hp based on possibilities.

People tend to forget that MILLIONS of dollars are poured into engineering cars and that your air box location was optimal based on all possible factors, being performace, air temperature, engine noise etc. and yet folks will still argue that you should replace that "restrictive" system with one that is outside of the heat of the engine bay. Remember, there is no cold air system that in and of itself is going to give you enough of a HP advantage to walk away from a similar powered car of the same weight. People install them for the look, the arguable HP gains, and on some rare occasions, actual better throttle response.
