Actually, the filter is cheaper than a tank of 100 oct in my area
After a few days with the filter in, I noticed that induction noise is noticeable louder especially when you get on the throttle. Also, the car seems much more eager to rev to redline. Not sure why but the response to mashing the pedal just seems a little different since the filter went in.
