CHEAP o2 Sensor
 

I just put new header on and couldnt get o2 sensor off of old one. I pretty much soaked it in solvent for 3 days and it wouldnt come off for nothing it was like it was welded in there.

well anyways does anyone know where to get a cheap o2 sensor at? I would highly appreciate it. not really feelin the whole waisting gas in the wallet area lol. THANKS

RE: CHEAP o2 Sensor
 

Soaking the O2 sensor in solvent or any other kind of lubricant or penetrating spray, will ruin the sensor.
I had the same problem myself. I wouldn't go cheap with them either, considering their importance in the correct functioning of your car.
Unless it's the secondary O2 sensor, which is not so necessary. Go with OEM parts as they seem to do the best work.
