Having drilled my airbox, I tend to agree that the only noticeable improvement is to the sound of the engine when accelerating. My throttle slack wasn't taken up until after the drilling, so I don't know if the wider-open throttle would have gotten enough air with the stock setup. I should also say that I drilled the airbox because I lost the snorkel while adding oil. Which might make one hesitate to rely on the wisdom of my opinions.
