Right...but from my understanding of the thread so far and him saying he ISN'T running the one that needs the extension since he doesn't HAVE the extension...means he has been driving around without his front o2. I thought I had mine plugged in once but I guess it didn't snap in and came loose. He isn't joking I was seeing around 9 mpg's. Easy fix though...you can also just splice the wires you have and extend them down a couple feet and wrap them in exhaust tape or header wrap.
