They run for about 50 bucks compared to the 200 for the OEM.

Are they any good?

NGK Claims that its a Direct plug in. So I might get it and it might help me get bette rmileage.

i do have over 170k miles on my 96 teg.

So what do you suggest?

Thanks

 

If your current sensor is out, replace them. I ran the NGK sensors in my old CivicDX (EX cat swap and needed new sensors) I didn't notice anything bad, gas mileage stayed about the same.
