it pretty much tricks the secondary 02 sensor and tells the car that the emmissions are running fine. you'll only need to run the defouler for the 02 sensor that is in the cat. I've had the defouler on my car since May and I haven't had a problem. in fact I'm getting better milage now. I was getting 330-360 miles on a tank of gas, now I'm getting 390-410 miles on a tank of gas.
