My D is going to turn 100k soon so looking to replace the pre cat o2 sensors. Is there any brands that are better to use? any good sites to buy them from? btw 2001 SLT 4.7l

 

From what I'm aware of the only 02 sensors our rigs like are the OEM brand.

 

I am sorry if this sounds stupid but what does that mean?

 

The Original Equipment Manufacturer part. Basically you would need to go to the dealer for them, or take a gamble trying to find the OEM part online.

 

OEM is Original Equipment Manufacturer. Denso seems to be it but I would call the dealer and double check. Nothing stupid about that question, its why we're here. Dang Mopar ya beat me by like 2secs posting, LOL.

 

Lol I'm bored out of my mind so im constantly watching the entire new post section and my subscribed threads. I constantly refresh about every three minutes.

 

Haha, I get those days too. Denso and NTK parts are the ones to use other than dealer. www.rockauto.com carries the o2 for the cheapest

 

I like Denso. $30 shipped from Amazon

 

Or amazon thanks dingo

 

Just whatever you do, don't replace it with a cheap Bosch O2 sensor from Advance or something. I made this mistake one time and it instantly triggered a check engine light and made my Durango stumble at idle and have no acceleration...

Denso is who Mopar uses for the sensor, so your best bet is either get one from the dealer or get a Denso from RockAuto. Usually, if you're not having a problem with the sensor though, you can remove it and use a torch to burn the crud off the end and insert it back in the exhaust!
