I am getting ready to change my O2 sensors, well at least the upstream ones. I am faced with a decision (money is tight) looks like I can get the kind you wire splice into old connector for $50-$60 cheaper than the bosch ones. Is it worth it to do that? Or bit the bullet and get the nicer ones? Be honest, I am on a budget. Maybe it will help you know it is not my daily driver. Thanks

 

Bite the bullet, save the headaches and get the proper ones. And also, replace all four.

 

Direct fit ntk with plug can be found on amazon for a good price
Downstream do nothing but trip cel if the cats stop "working"

What makes you think you need o2 sensors?

 

It threw codes for o2 just didn't list them here in another post called d1 issues. I thought I read somewhere the downstream sensors rarely go bad is that true? should I really change those.

Engine is really lacking on power, I have cleaned everything possible I can engine wise, o2's have to be next in line. Already done new plugs and wires too.

 

Do you have the part number for the NGK sensor?

 

You read bs. Not true at all. Take the best two that you don't have codes for and use those downstream until you have the funds to replace them.
