JDM intake fuel saver

This device looks really cool.  I got mine and was excited to use it.  The first thing I had to do was spray WD-40 on the shaft and turbines because they didn't spin very well.  I got it to spin good and put it in my car's air intake.  After driving for a little bit, I started to worry what would happen if one or more of the fan blades broke off and was ingested into the engine.  I removed the device and I feel much better not having it in my car.  Bottom line:  it may save gas and gain a few more horsepower, but it's risky to have moving parts inside the air intake.  Best to you!
