Oxygen Extender

[joshs360]

Can anyone tell me if they have had luck with out putting on a oxygen extender. I am unable to get the o2 sensor off of my exhaust. I have tried penetration lube also heating it by letting the car run for a bit then tried to remove it then with no luck. I also tried to heat it with a torch and get it lose when it was hot then with no luck so my question is there anyone out there that has not had to put any modification to their sensor and still had luck

I'm not using an extender but an O2 or EFI enhancer.... but I might just use the extender as well

Using an O2 extender is a very crude and ineffective way to remedy your problem. Use an Effie and your able to offset much more effectively.
