Ok Napa shows a bunch of O2 sensors for a 1998 1500 4x4 5.9 vin Z but they show left or right & post cat but my Ram I believe from the manual that is available here on Dodge Forum that I have the HD 1500 because I have one O2 centered between the Y at the converter & one about 10 inches after the converter & not the 4 O2 sensors that Napa shows.

Could someone help me out & let me know what the O2 sensor part #'s are for my application?

Thanks a bunch in advance!

 

the one before the convertor i have a Bosch part# 13100 and the after cat sensor is is Bosch part# 13280...

use them part#'s and you will be fine...

 

Thanks a bunch, just picked them up & put them in, cleaned the tb & it runs 1000 times better. Will go on road test in a few hours.

 

whats the difference between the o2's?? i dont understand they should both be doing the same thing, sensing oxygen wierd.. i have the same o2 setup as you scout
