I need to swap out my front o2's before I go back to the dyno. Can I do this at home with a tool set? Thanks.

tech there is a 02 sensor socket that you should use so you don't damage anything but the hardest part is taking off the connectors and make sure to spray some wd-40 or pb on them before you tackle...

This sounds extremely noobish, but looking thru my Haynes repair manual, it just shows the rear ones. Where are the fronts?

Just further up the pipes then the rears. It's one of those things you'll be able to see easy when you get down there. Personally I had a open ended wrench that fit perfectly and had no problems with that, but yeah, they are gonna be pretty damn tight.

yeah there right around where the mid pipe meets the manifold, and there between a PITA and annoying so good luck

Alright. Thanks guys, I'm gonna fix that up this afternoon. Ford replacements, or aftermarket?

If you are planning on getting Long Tube headers later on, I suggest you buy the Bosch o2 sensors with the 16" length wire. That way you wont need O2 extensions. Dont buy Universal O2s, get Bosch. I got mine at Advance Autoparts for like $50something each. And length of wire wont change the price. Removing the O2s really isnt that hard. Hardest part would be disconnecting the passenger side one. Good idea would be to buy the O2s first so you can see how the plug clips on cause you will basically have to unplug them by feel. After you get plugs disconnected you can use a 22mm open wrench (think that was the size, not %100 sure). Once you loosen the O2 with wrench, you should be able to just unscrew them out by hand. Be very careful when installing the new ones, try not to dirty the tips of the sensors and screw and tighten them in before you plug em in. Also make sure you turn the wires while you are screwing in the O2s so then dont twist and break. Hope that helped some, GL.

Thanks man. I was told by my tuner to NOT use bosch. I'm not really sure why. So, I'll be picking up some overly expensive motorcraft crap. Thanks for the install tips. Should be too bad.

Hmm, now you got me worried, lol I would love to know why he didnt want you using Bosch!

There is persistent and completely unfoundedprejudice against Bosch O2 sensors--those who spout such nonsense are fools as Bosch is the OEM manufacturer for well over 1/4 of all makes. Also, as one of the worlds largsetsensors manufacturers theymake the actual sensing elements.form many other O2 sensor "manufacturers" that are actually assemblers.[/align][/align]I think in part the wive's tale continues becuase Bosch sensors are commonly sold at your FLAPS, installers stand a better chance of getting your money and a markup on the part by steering you away from doing it yourself...I have used Bosch sensors almost exclusively for well over 10 years, the 4-wire installed in my '92 Miata had over 85k miles on it when I sold the car and it still worked fine.[/align][/align]BTW, all narrowband platinum/zirconum O2 sensors are the same electrically--thay have to be as the signal they generate is created by the same chemical reaction. [/align][/align]Lookee here for more than you ever wanted to klnow about narrowband O2 sensors.[/align][/align] [/align][/align]Oh, you may want to consider paying a local muffler shop to install the O2 sensor, sometime on older car they do NOT want to come out. The muffler shops deal with this every day and can if necessary heat one side of the bung to red hot with an oxy/acetylene torch--this will expand the bung and even the most rusted in sensor will come out without bring the bung's threads with it (as is common when using brute force alone).[/align]
