Default 2002 Mustang GT O2 Sensor Replacement

I've been informed that my 2002 Mustang GT has faulty O2 sensors (most likely) which explains low-speed stuttering during acceleration. I'm going to replace the O2 sensors myself, from what I've read they're a very easy job to do yourself with this year/model.

I understand the stock sensors are actually the most compatible sensors on the market, as other aftermarkets can raise false engine lights, especially with the flowmaster aftermarket cats installed.

Should I pony up the 75-80 bucks for OEM sensors? Or are there better aftermarkets that are cheaper or get more bang for the buck?

I prefer the OEM ones from Ford but sometimes during that last min i've had to go with other's. i've never had problems with the Bosch 02's.

Ok well I got Bosch OEMs from Napa Auto parts, but the bad news is that they're actually larger than the ones I had previously installed, and I couldn't get the old ones off, anyway. I'm taking the car down to the shop tomorrow for a quick swap- it's easy work if you can get the car on jacks and hit it with a torque ratchet job instead of trying to do it laying on your back under a bunch of cribbing.

My OEM's ('99 GT) were NTK.
There's a lot of debate about which ones suck and which ones don't suck. If you got the OEMs for $75 or $80 bucks then you got a good deal. I went to Ford and they wanted $120. For ONE.

yea can be a pain if you dont have acces to a pit or lift. let me know if it clears up your acceleration, because that almost sounds like a cop

Well, it went great and the car's running about 10x better now. Note: occasionally, your O2 sensors might get stuck in the bungs. I didn't have this issue, just be ready to spend another 50-100 bucks if they accidentally strip your screw bungs and they have to weld in new ones. Just an FYI for folks.

True as with anything but if you bought motorcraft or prolly most other top name then they come with anti seize already on the threads but as with anything always a better idea to not strip it

So it was the O2 sensor that was wrong with your car? But didn't you say you didn't have a ses light that triggered or you did?

Also one more thing crzyhorse you said I might need a tune because of the K&N fipk2 so would you guys recommend the SCT X3 or the SCT SF3?

Anti-seize is good stuff, too.

i belive those are the same tuners however i may be incorrect

i just got the X3 about a month ago after i got rid of my diablo
from AM or breenspeed or other places you can get these with 3 custom tunes for about 375 plus you will gain a little torque and if you et gears or anything that would require a tune for our car you can fix it all

i dont think you will find anyone on here tell you to not buy a tuner
