I installed my cai a couple months ago (cheapo ebay one), and it fit fine except for one sensor, the hole seemed to be tapered, so the sensor wouln't go all the way in. It started fine and I got it as far as I could with a wrench, made sure it was oriented properly, and forgot about it until today when I was cleaning up the engine (see link below). Not to start another mileage thread, but could this be why I'm getting 12 mpg with very conservative driving? It is lined up correctly to recieve air flow, but I'm not sure what it is so I dont know how it might affect anything. I haven't noticed any differences in anything as far as power, idle, etc. Any help is appreciated. http://img169.imageshack.us/my.php?image=sensor3eq.jpg
