    Review & Installation Video

    Review & Install Video

    The NTK Performance Oxygen Sensor is available for any '99 to '09 V6 owner and '99 to '04 4.6 liter owner, who's in need of a replacement for a bad front sensor in order to turn off the check engine light, and improve engine performance and exhaust flow. It's a pretty inexpensive upgrade coming in right under the $30 mark for this sensor. The installation doesn't take too much to complete, so, expect one out of three wrenches on our difficulty meter which I'll show you later on. A bad oxygen sensor can be the bane of quite a few issues for your New Edge and early S197. If you're experiencing a poor performance, like engine bogging down, feeling sluggish, or if you've got a lousy fuel economy and the check engine light is on, then you probably need a new O2 sensor. If you've got a tuner or a code reader, you'll be able to tell which "X" sensor exactly needs to be replaced, if that's the issue. If you've narrowed it down to a front or upstream sensor, then this is the perfect upgrade here because it is a direct fit replacement. This particular O2 sensor from NTK was designed with a waterproof factory-fitted connector to ensure a long-lasting performance and a perfect fit each time, since it is an OEM styling. With a bad factory O2, you'll most likely fail your local emissions test, if it applies in your area. It is pretty straight forward, so you should be able to tackle this one and take care of it yourself in your driveway. This one, you can pick up currently for just about 26 bucks which isn't a bad price in my opinion. The install, since it is pretty simple, will get one out of three wrenches on our difficulty meter. This shouldn't take longer than about an hour or so. But, I say, you can probably get it done in a little less. You need a jack and jack stand to probably secure the car in the air, and you'll need a ratchet and an O2 sensor socket since it is a specific one, or you could just use a 22 millimeter wrench. Once the Mustang is in the air and it's supported on stands, you can use your O2 sensor socket or wrench to remove the old sensor from the exhaust manifold or headers. Once that's removed, you can unplug the other end from the wiring harness, of course. The NTK Sensor is built to be a direct bolt-on like I said a bunch of times in this video. So, you should be able to just pop it right into the same place using the same tools and plug it into the same stock harness, and you'll be good to go. Just to wrap this one up, if you're the owner of a '99 to '09 V6 or a '99 to '04 4.6 liter Mustang, you might wanna check out the NTK Performance Front Oxygen Sensor, which is available right here at

    Regain Lost Power. A bad oxygen (aka O2) sensor can cause poor performance, lousy fuel economy, the dreaded check engine light, and even cause you to fail emissions testing. So replace those worn out sensors with brand new NTK sensors for superior, consistent performance.
    Exceeds OEM Quality. Designed with a waterproof factory-fitted connector to ensure a perfect fit every time, NTK's oxygen sensors meet or exceed OE specifications and are built with the highest quality materials and craftsmanship to ensure a superior quality direct replacement for your worn or failed OEM sensors.

        hello I have a 2003 mustang gt an I wanted to know how many o2 sensors I would need my service engine is on an it pulled up the o2 sensor code I want to replace them just need to how many I need to replace.

        • There are several O2 sensor codes you can get, and the code will tell you which sensor circuit the issue exists in. In the code description you should see bank and sensor. Bank 1 is passenger side, Bank 2 is driver side. Sensor 1 would be your upstream/front O2 Sensor, and Sensor 2 would be the back/downstream sensor. For example, Bank 1 sensor 1 would be the front sensor on the passenger side. Keep in mind that other factors can also effect this, such as corrosion in the wiring or connectors, or damaged/broken/shorted wiring.

        how many o2 sensors do I need for a 2004 mach1?

        • You have two pre cat o2 sensors and two o2 sensors after the cat. The two pre cat o2 sensors are for your air and fuel mixture and the two after the cat are for telling the ECM that the cat's are working properly. If your car is running bad and you are going to change any o2 sensor i would change the two pre cat o2 sensors (closest to the exhaust manifold) with the NTK o2 sensors from American Muscle. NTK o2 sensor is a great product. Ibanezshaun Year: 2000 Model: V6

        Where would the bank 2 sensor 2 be located on a 2004 v6 mustang?

        What is the NTK part number on this?

        • NTK's part number is 22060.

        Hello I have a 2000 V6 Mustang, my check engine soon light recently turned on and as I went to a local auto parts store they told me that it was because of my oxygen sensors, they just didnt know exactly which one, they said it was a code 1131. Now I am looking into buying this, however I dont know how many upstream or downstream sensors I need, or how many the mustang even has. If you could please get back to me I might just buy your products if you guys carry both upstream and downstream sensors :)

        • If you have a bad O2 sensor, a shop should be able to let you know at the very least if which bank/sensor is bad, relative to the code being thrown. So, for example, if bank 1 sensor 1 is bad, this sensor would do the trick as "sensor 1" refers to any of the sensors up front/before the catalytic converters.

            Definitely is efficient. I’m getting much better mileage now that I’ve fixed my exhaust leaks and replaced my bad O2 sensor. Last one was FRIED on the harness completely. Really good price and good quality.

            What You Expect

            My old O2 sensor was throwing a code so I replaced it with this one and haven’t had any problems. Hardest part about the install was getting the old one off, I ended up having to put it on a lift, couldn’t get enough leverage under it on the jack

            No issues. All appears to be operating well. A little tricky with the ordering. Mach 1 requires 4ea. O2 sensors, i.e., 2 front and 2 rear.

            The 02 worked perfectly. The best part is that I have long tube headers, and the pigtail had the perfect amount of length, so that I didn't have to rig anything up, and was a perfect fit!

            Bad quality stay away!

            Bought these because my car would not idle. After replacing with these, one o2 sensor would heat up faster than the other and cause the engine to cut off until they both heated up. Ended up having to spend even more and replace them again with genuine Ford motorcraft. Now my Mustang runs and idles perfect. Stay away from this brand.
