I've tried that too and I totally agree, its really really loud. I must say though, I LOVE the burble it makes at 2-3k rpm. Too bad the engine seems to lose a lot of power while doing this; I had to practically floor it to climb a hill that usually gave the Focus no problems. I'm curious what this intake would do, it doesn't seem to suck in air from any lower in the engine bay than the stock one. (Its not curved down towards the road like many I've seen for other cars)To what degree would you say it has increased intake sound (i.e. 20%, 50%???). Just curious because I drove for a couple of days with the top cover off my air box and found it was too loud for my liking but that was with the stock filter.
