O2 sensor
I tried to search the topic but O2 seems to be too short for the search engine. Its about time for me to replace the stock sensor and I was wondering does an aftermarket one make a difference? where might be the cheapest place to get a stock o2 sensor? thank you

My 2cents, If you do get a universal o2 sensor and cut the connector off of the old one, you shouldn't use butt connectors and just crimp them toghether. You should sauder (sp?) them toghether and cover with heat shrink tubing. Reason being that the butt connectors can change the resistance in the wiring and this can mess up the signals going to the ecu. I have had this happen to me before on another car. o2 didnt read right with butt connectors inline.

This one already has the connector on it. some people have had problems with the solder holding a clear connection. The one at this website is $45 and free shipping. I ordered this and it came in two days... they didn't even charge my credit card by the time I got it.

Good advice here. Moehler posted the link to the Walker o2 sensor with the oem wiring harness. It's only $45. I think in this case it's better to pay a little more and avoid any wiring issues.

I got one from the Advance auto parts. 19 bucks. I did have to splice it in, in order to use the connector. It works fine for me, I have no problems with it.

The wire does not melt just as the vacuum hoses don't melt, but both do dry rot and crack as can be seen with the failure of the vacuum hoses and engine wire harnesses.
Silver has a much higher melting point at around 1200F and will definitely not separate due to engine heat.
