    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.

    What is the warranty on it.

    • The NTK Performance Oxygen Sensor has a 1-year warranty.

    I have long tube headers with a off road xpipe and or no cats. Do i need the rear o2 sensers since they supposidly just read the air fuel to see if cats are working wich they arent there and will throw the code... Or would i be just as good getting 2 front o2 sensors and pluging the rear? I have none hooked up as of now... I know front 2 will make a difference but i dont think rears will. I could save the money for the screamin deamon coil pack and a tuner....

    • Rear O2 sensors will need to be retained or deleted electronically prior to complete removal. Front O2 sensors must be retained as these are crucial to your engine determining the correct air/fuel ratio.

    I'm wondering, there are four wires on this sensor, two white and two grey. If installing on the rear, to which factory wires do the o2 sensor wires correspond to. I'm asking because the HEGO connector from the factory harness is broken off.

    • Unfortunately we do not have a listing for the O2 sensor wire colors, as these can vary from year to year and between GT, V6 and Cobra models.

      Right on the money!

      I had the check engine light on and it turned out to be the 1-02 O2 sensor. I bought the NTK version of the sensor because of its good reviews and its price, which was substantially cheaper than the competition. Installed it and everything is back to A-OK! Now we will see how long it lasts!

      NTK Performance Oxygen Sensor(94-04v8;95-09 V6)

      I purchased the NTK oxygen sensors through American Muscle and they were an easy fix to my high RPM missing problem as well as my Idle missing problem. I just sprayed the old sensors with penetrating oil and waited 5 minutes. The old sensors were an easy out and the new sensors came pre-lubricated and screwed the new NTK sensors back in and the easy connections solved all my problems. Now my 02 Mustang GT is back to quick launches and steady idles!

      Bought two of them, installed at the same time and one went bad after less then 2 months. No warranty, so now I will be buying new one for just a little more from O'Reilly's because they actually have a warranty...

      Easy Install and Improved MPG

      I had a bad sensor in left rear, bank 2. Car was throwing CEL too. Ordered all 4 replacements for front and rear those had about 91k miles. These were recommended as OEM. Install only took about 10 minutes although, I did have to use a little bit of blaster on the right rear sensor to get it off. After install I drove the car immediately and it seemed to have much better throttle response and MPG too.

      These work for 05-10 Mustang GTs

      Installed these with no issues and no check engine lights. I called American Muscle and they confirmed that these work with the 05-10 V8 4.6L engines as well even though the website says they will not fit. They are plenty long for the Kooks long tube headers without the extension. Buy with confidence!!!
