Looking to buy a front o2 sensor for my 04 Rx8.. Its really making the car run like
crap.. The only one I found is from Bosch and its 325$.. Please someone let me
know.. New or Used is ok with me...

 

One source for OEM brand new front oxygen sensor. ~$256 should be shipped price unless you live in NC. I don't think I'd buy this item used. I'd like to know how the install goes.

PS: I've order from Jason @ Montgomery Mazda, but I'm not affiliated with the place.

 

^+1...the installation should only take a couple of minutes, just use an adjustable wrench, it might be hard to turn due to all the heatin and coolin the pipe goes through.

how do you know its your o2sensor?

 

CEL told me when my rear 02 sensor went bad. I'd guess drmazda has a CEL for the front sensor.

 

I had a friend code scan it and all 3 codes were from front o2 sensor..
Malfunction, Low voltage, and system to lean codes were thrown..


is it really that ez to replace,, i crawled under it and it looks like I may have
to unblolt the exhaust manifold to drop it some..

 

i my have a used one for you in a few days ill let you know ill sell it cheap also
