O2 sensor
 

Hey everyone. I have been trying to change out the front o2 sensor on a 05 wrx. I tried PB blaster and o2 sensor wrench. I was even hitting the wrench with a hammer. Any tips to get the sensor off. Any help is much appreciated.

Thanks,

Lance

I may be a little late, but if you're gonna change it anyway. I say cut the wires off from the o2 sensor and use a deep socket to get it out. Goodluck

Make sure you have a good socket sensor wrench, and try to remove it when the sensor is hot (just after turning off the car).
