I have this thing on my car, but don't really know if it really works. I've read here somewhere on the internet that it restricts air flow and loose power but since Im getting about 21.5 MPG in a 94 New Yorker, I dont know if I should remove it and see if I get more power and milage or if it is really working and leave it there...What do you guys think ?? Thanks.
