So I finally threw a sensor code... was wondering the views on what I see as the 3 main options.
Bosch
Walker
NGK

figure since I threw the upstream passenger side I would just go and do all 4. at the same time. Just curious on your thoughts on these manufactures.
thanks

 

I have used bosh with no problems, Check amazon for cheap prices...

 

Use the factory Bosch, I've used other brands before and found the Bosch worked the best for me. Here's a link to them on amazon.

 

Any major brand name, they are all built to the same specs.
Just do not buy the universal 02's with no plugs, and yes Amazon will get you the better prices.
How many miles on your truck and are you re[lacing them all?

 

Bosch has been good for me. I don't see why you would do the post-cat sensors because those are just pass/fail for the emissions system; the upstream sensors are the only ones that affect the A/F ratio when running closed loop.

 

Mike that is what I thought, but wanted to see what people have to say about different brands and yes I am going to replace all 4...mileage is 121k. added in that I am up for annual inspection.

 

Dont bother replacing the rears unless you have codes for them, they do nothing other than monitor the cat's.
Save your money for something else.
No it wont hurt to replace them, but if they are not bad why bother?
Just do the front two.

 

Replacing the rears could possibly even cause headaches later. A lot of o2 senders start reading lean over time, so they might not detect a failing cat as easily. If you replace them with new, you might find out you need cats too.
