where can I find them where they arent 90 bucks a piece and how many of them do I need I also heard on here not to go with Bosch anyone have any opinions because my drivers side manifold is leaking because there is a ticking sound and its pretty much constant and I can see a break in the gasket that seals it to the engine I know Im probably going to have to replace this to pass emissions in march

Unless you're getting codes for your O2 sensors or you're nearing 100k miles, your old ones should be ok. If your exhaust manifold gasket is bad, that's where your problem is coming from.

Im nearing 100k miles soon im at 92k now so Im just tryin to figure out if I have to buy the motorcraft ones because they are twice as expensive for just one

While it's recommended to stick with Motorcraft, you can run to your local auto parts store and most of their O2 sensors should work fine.

well you can go this route but a lot of people will just say dish out the cash and get the motorcraft ones.

The Ford parts are going to probably be best in terms of efficiency, quality and longevity.

I was looking for a new gasket for my IAC and I was on RockAuto.com and I figured I'd see what they had for O2 sensors. It just so happens they carry Motorcraft for about $60 each. Not as cheap as one from your local auto parts store but it beats $60 and RockAuto is a great company. I tend to order things in the evening and as long as they're in stock they ship out the next morning
