Is there a diffference in these sencors up stream versus down stream

Lenny is correct. The upstream and downstream are typically different on GM vehicles (Chevrolet, GMC, Pontiac, Buick, Oldsmobile to name a few). I never have understood why the sensors are different; externally only the electrical connectors are different, but maybe internally there's a difference...I don't know. What I usually do is use another website, typically RockAuto.com, to look up part numbers. The description will tell you UPSTREAM or DOWNSTREAM. Then I bring that part number to Amazon and see who's cheaper. Typically Amazon is since RockAuto charges shipping and sales tax (at least for me anyways; in WI). Lenny, you got lucky! I replaced all my O2 sensors on my K1500 Z71 and I'm still at 16-17mpg tops; hit 20mpg once doing 60mph for a 400mi trip.

Sorry my friend. I didn't make any comparisons. I just took a leap and am happy with the purchase.

I would be suspect if there was a noticeable flow difference. My experience has been that new filter cartridges produces a better flow for a while and gradually diminishes.

I would say they're comparable. I haven't detected a difference between the two fans.

I believe the only difference is the color. Different colors sell at different prices from time to time.

Yes there is if you look at the connector on them you will see one is a 4 prong male and one is 4 prong female also it should say witch is upstream and down stream ,have a look at your old ones BEFORE you order.save your self trouble by making sure you get the right one the first time

Refer to this Laticrete Converstions Blog from 2010. The differences are subtle, but clearly explained. http://laticrete.blogspot.ca/2010_05_01_archive.html

Hi. I have nothing to compare them to but this is exactly why I purchased them. They seem accurate. Good luck!

Interestingly: lower. This goes against conventional siphoning logic, but these work on a different principle. The water doesn't have to be much lower, as long as the surface of the water is slightly lower than the base of the spike you're good.

I have both, as far as I can tell there is no difference. They both work the same. Buy whichever cost less. I think it's more of a style thing...

As near as I can tell they are about the same. I have had no ware issues with either type, as long as they are kept clean of dirt and sand. hope this will help.

On this particular brand and style, I have seen no differences between the lower and higher priced faucets. I love this one!! I have seen some others where the drain cover is of a lower quality, and they do look terrible with use in our area due to the hard water. Also, the color indicator for the water temp can wear off with a lower quality faucet, but I have seen it occur in a higher quality faucet as well. All in all, I don't see much difference be in my opinion. Buy this faucet, you will love it!!!

We were concerned about the same thing. We actually ordered the next size up from what was recommend in an effort to avoid loss of pressure. We're very pleased with the filter. We notice no pressure difference.

No difference that I know of. I have been using them for sprouting for months with good results.

none I think it's the year I looked at both there is no difference I could find .

Yes they are different. They are thicker, have less dexterity and have insulation.

The water pressure is good, will be close to the actual pressure that you have with maybe a little bit of improvement. nothing noticeable for me.
