Need upstream and downstream are they the same?

Honestly? I cannot say for certain. I am not an authorized Dodge mechanic. However I have ALWAYS worked on my own vehicles and I would suggest that you get the O2 sensor that is required. I would suppose that they are calibrated differently. generally one is upstream of the cat ( towards the front of the engine) , and the other is downstream ( towards the exhaust). Another indicator is the fact that they are specified upstream and down stream and generally vary on cost.

I suppose it depends on the vehicle, but in my 1998 Jeep Wrangler TJ, this is the upstream sensor. The downstream sensor is different, and its part number is Bosch 13138, though if you're buying for a Jeep I would recommend you stay away from from the Bosch and go with NTK/NGK. I've been much happier since I switched.

No, there is two different part numbers for up and down stream. Best way is to look it up on part store website, then match up the part numbers here. That's what I did.

In my setup, that's taken care of upstream, in my Oppo player. In other setups, I don't know.

This Oxygen Sensor is a universal part that can be installed either downstream or upstream. Please be advised that this requires minor modifications.

Will not work for either upstream or down stream! Upstream bosch 15717. downstream 15729.

No ... But you must have the proper psi downstream for the pump to work .. The psi is listed on the pump instructions ...

No downstream leaks here. I can't imagine what would cause that other than age and corrosion on the line.

2 filters. Make sure piping leading to filter has enough volume so that when the flow is reduced at the filter the backpressure doesn't cause the water to backup at the source.

You can divert to one or the other, or both. When you do both the water pressure is half on each side.

Yes. A filter is recommended, but the connection can be made directly to your supply line.

Upstream on the Sentra SE-R. I installed this on my SE-R. I believe the downstream has a different connector (I haven't changed this one yet). I don't know about other vehicles. I suggest that you do as I did and go to Walker's website and do a search. This verified what Amazon stated on their website. This will save you time and more importantly frustration. I hope this helped.

I can't speak for your car but as I understand it, upstream is the sensor closest to or before the catalytic converter and others after that are referred to as downstream. Sensors after the cat are not very important and although they might turn on the "check engine" light, they will have no effect on the engine performance, they simply measure emissions. I know some in the know will solder a resistor in to negate the unit so it won't turn the light on. The upstream sensor is the important one. It would seem to me that if the connectors going to the sensor are the same colors then I would install the same sensor whether upstream or downstream. If the wire colors are different, then I would assume that the sensors are different. Hope this helps and good luck. Bob

Where the water lines (PIPES inlet/outlet) attach (Bottom) one has a hook up 1.5" pipe the other has a 2" hook up.

You could if you wanted to; the upstream router would get none of the Skydog functionality. You would just need an Ethernet cable, nothing special.

This sensor is both bank one and bank two sensor 2. Sometimes referred to as left or right, upstream and downstream. These are the downstream ones.

No minimum flow necessary. There is a built in trickle gauge so you can monitor all water flow.

Will work either location. Be careful not to create backflow if used underground. Draining to prevent freezing could be an issue if underground
