You mean electric hand drill. It is much easier than you would expect, just hold the airbox between your legs while standing up and drill with a holesaw which has a guidance drill bit inside. Make sure you mark the center spot with a white marker or similar. Use a high-RPM drill (non battery operated) in order to cut perfectly in that plastic.
