NTK Performance Oxygen Sensor; Upstream; Front (99-09 Mustang V6; 99-04 4.6L Mustang)

Video Review & Installation

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 americanmuscle.com.
