So i threw a code recently....so i took my car to get checked and the mechanic told me that the front oxygen sensor is bad. My problem is I am wondering if the front refers to before the catalyst or after?? Also, what brand should i go with, because i checked on a website and it says there are two OEM ones which are made by Denso and NTK. Also, they have bosch but it looks much more complicated than the ones from Denso or NTK...Can someone clear this up for me thanks.

 

Front is the primary one before the cat. I've heard stories of the Bosch ones being junkassshit, i got a denso.

 

thanks

yea ive seen bosch ones last less than a year...sucks

where can you get the denso ones?
cause i thought those were stock and only avaiable at the dealer for a bargain at 190 bucks

 

I bought it online, i dont remeber the site, It's pretty expensive though.

 

autozone carries the denso 02

 

I just bought an oxygen sensor from this site and it seems to be working pretty good, it was also the cheapest price I found.
