The drone Is heard in the engine bay. Its at the throttle body I believe. Its getting kinda annoying. Then again I drive on the autobahn at 90+ MPH

This intake is anything but made only for the 128i, which is a BAD THING. It doesn't fit right in and it requires some modification.

It's hard to explain the drone. At 2k rpm you can hear it but its minimal and I actually like it because it gives the engine a nice hum. Its a deeper than stock engine sound. At 3k it there again but even less that at 2k. It barely noticeable and other people can't tell. Like I said at around 4K is the bad drone. The drone is loud at about 15-50% throttle. The percentages are a guess of course. When you are at about 75% throttle or higher there is no drone. Its like an obnoxious hum sound. I can't sit in that drone for long without getting annoyed.

nope not a clue. I have not gotten it dyno'd. Anyone have a stock 128i dyno'd and know what the lose is...i.e. power train lose. I will be getting it dyno'd before and after I get my ecu tune, but that will be with a CAI and exhaust.
