I'd say no but it will get debated. If you put the ability to have more air going into an engine, then you need more full to balance it out. Otherwise, you will run lean. But, you will make more HP, so theoretically, if you have more power, it MAY take less fuel to go from point A to point B all things being equal. Then, you have the so called CAI's that are glorified hot air breathers in that they are NOT ducted to the outside and they just suck hot air. Those HURT EVERYTHING. So, the answer is........NO and YES.
