Has anyone used an aftermarket O2 sensor in their 3.0?

I just got some codes that point to my passenger side O2 sensor. Thinking about a cheaper splice type. Just wondering if anyone had any problems with them. Also, I just want to verify that we do have 4 wire sensors, right?<ul><li><a href="http://www.ecstuning.com/stage/images/dis/7072/600/7072.jpg">http://www.ecstuning.com/stage/images/dis/7072/600/7072.jpg</a</li></ul>

The pre Cat are very important!!! Don't buy cheapos or splice an universal

one. Get the OEM ones for peace of mind.

I would. Check EBay for Densos. Dirt cheap.

I bought two Bosch BS15733s for $99.60 shipped at Amazon. Couldn't pass that up

Others at on the TT forum have had good sucess with them and I'm about to be laid off in about 10 days, so these will have to do.

Re: Which codes? 16815 or 16805? I just got those recently.

I just these:

17978 - Engine Start Blocked by Immobilizer
P1570 - 008 - Implausible Signal - Intermittent
16815 - Warm Up Catalyst: Bank 2: Efficiency Below Threshold
P0431 - 001 - Upper Limit Exceeded - Intermittent
17524 - Oxygen (Lambda) Sensor Heating: B1 S1: Open Circuit
P1116 - 004 - No Signal/Communication

I may actually have a bad CAT but the O2 sensors were way over due anyway. I've got 155k on the clock.
