[Supras] O2 Sensor + 3 inch elbow

[Martin Dubois]

Hey guys, a quick question since I wasn't able to find the archives.. :P

 

I'm looking to change my O2 sensor since it's as old as the car itself, and
my gas mileage is fairly poor.  I found a generic O2 sensor on E-Bay for
about 30 bucks.  First of all, are the generic sensors anything I should put
faith in?  Or should I just go get raped by my local Toyota dealer?  It has
four wired on it.  Aren't the Supra's 3 wires?  Does this make a difference?
Sorry for the ignorant questions.  I'm just a "shadetree" mechanic ;)

 

2 nd, I'm also looking for a 3" turbo elbow with O2 sensor hole. Either used
or new, it's all good to me.  If anyone has one for sale, I'd be interested.
Shipping would be to J1J 4H9, Quebec, Canada.

 

Thanks in advance for the replies!
