    How many O2 sensors? How many front and rear O2 sensors would I need for a 98 V6 Mustang? Please help!


    • Eduardo, There are a total of 4 oxygen sensors for your model. There are 2 upstream of the catalytic converters and 2 downstream of the catalytic converters. If you don't have catalytic converters installed (i.e. you installed a off-road H-pipe or X-pipe), you will need to purchase the MIL eliminators to "trick" the computer or your check engine light will come on.

    I have a 2007 V6 and I want to replace all O2 sensors. How many do I need?? front and back? and will this one fit only rear or both?


    • This NTK Performance Oxygen Sensor will replace your downstream (rear) O2 sensors, of which you will have 2. The NTK Performance Oxygen Sensor linked below will replace your upstream (front) O2 sensors, of which you will also have 2.

    I'm using foxbody style long tube headers on my 94 gt can i use these o2 sensors and would I need extension harness


    • The NTK Performance Oxygen Sensor are designed for fitment on 94-95 V8 Mustangs. We have not tested these on a fox header, or on a fox header in an SN95 to confirm fitment, however if they properly thread in and do not have clearance issues, you will require O2 sensor extensions due to the revised O2 sensor location.

    I have a 2005 V6 and want to replace all 4 sensors will this fit?


    • The NTK Performance Oxygen Sensor - Front (94-95 5.0L) - Rear (95-09 V6; 94-04 4.6L) will fit the 2005 V6 mustang how it will only fit for the rear sensors. You will need NTK Performance Oxygen Sensor - Front (99-09 V6; 99-04 4.6L) item number 64044 for the front.

      fit well on my 2006 mustang v6, and works well - runs much smoother. cords were a bit too long (I have a Ford performance dual exhaust and some aftermarnket cats), but good overall

      A true performance part!

      Only took me 10 minutes to remove and install the old and the new. There was an immediate notice in my performance and gas mileage. My car was dragging on inclines and even shut off. Now that I have these installed these issues are gone! Thanks AM!

      Good upgrade

      Good upgrade if one of your sensors has gone out or if you haven't changed your old ones Ina while. I've also noticed a slight difference in mpg.

      Went overboard in a good way

      Was using Mil eliminators for a while after installing Headers, Mid Pipe (flow thru cats) and exhaust to turn off the service engine light. Just replace all O2 sensors. I'm good to go. A/M only sells whats right for your stang
