I am following everyone's lead as I am new to this car. But I am all in. Now if someone could explain to me in layperson's terms what is the Needswings cold air intake. Without getting too technical on me will it help my performance. I have owned for 1 month a 2007 coupe, automatic, 29,000 miles. I noticed that when I accelerate, that is push on the pedal from a dead stop there is a slight lag. Nothing real noticeable but I noticed the power seems to be lacking from my other cars. Will the Needswings cold air intake along with the Eurocharge assist in this.

One las question. In all of my reading on this forum people keep referencing a car as "NA" or "N/A". Can someone please explain what is that referencing.

Sorry I know my questions are base line and I have really tried to use the Search feature.

The ETC (Electronic Throttle Control), otherwise known as "Drive-By-Wire", causes a delayed response and subdues acceleration, creating problems in situations such as quick gear changes, pulling into traffic, passing other vehicles and up-hill starts.
The Sprint Booster Power Converter eliminates this delayed throttle response and provides immediate on-tap acceleration whenever the driver demands it! Most cars have a 1 second lag between when the pedal is pushed and the car actually responds. The Sprint Booster corrects this problem instantly giving you all your vehicles power with no hesitation.
