I'm really failing to see how drilling into the airbox would increase horsepower. The air filter/box is not a major restriction on the 944 (it might be different on the 968, admittedly). The amount of air that gets into the engine is regulated at the AFM box, which is located AFTER the air box. So it doesn't matter if you get more air into the box - the AFM will only allow a specific amount through anyhow.

If we are talking about COLDER air, it is POSSIBLE that colder air would get you better HP numbers, but we are talking about negligable results here. ACtually, I would think this would make a bigger difference on a turbocharged car than a NA one.

If people have done this and have gotten tangible results, then I guess it works (unless we are seeing a Placibo effect here)... I just don't think I understand why it would make a difference.
