Needswings has the best system I've seen to date for our cars, at least that pulls air from in front of the radiator. Again I question the design mainly the filters which are not aimed in the direction from where air can be forced into them. They seem to end up sideways where the stock system has the intake lines aimed front ways. If I'm off base here let me know.
You are not, Pat. Needswings is a good choice.
Eurocharged has theirs sucking air from the front right fender box. This is down low where it is colder and clearly outside the heat of the engine. Downside is that you might have to worry about hydrolock in heavy rains.
Another point is that the aftermarket CAI are larger, up to three inches, and have smoother, less restrictive elbows.
You know there is a difference because the airflow sensor must be adjusted to deal with the change. It is also a good idea to increase your injector's capacities.
