Hi, anyone have a used o2 sensor that they are not using, I'm currently running with a L2H2 and it's not working very well. Please make me an offer. Thanks

Any one, or atleast where i can buy one? and which type? i noticed there was a bosch l1h1 on ebay for around 300, is the bosch the right type of o2 sensor for a replacement?

thanks
