Why is the upper O2 sensor for a 98 civic hx manual transmission so expensive (approx. 300 & up).

Is there a substitution that can be used? Anyone have suggestions?

 

ya cheaper aftermarket sensors from autozone. or search for local junk yard for a replacement if ya want to try and be cheap, tho used ones in the manifold can be a huge PITA to remove at times! the autozone cheap new ones probably wont last as long but alot cheaper!

 

um...i purchased my primary o2 sensor for like 70 and some odd change. (bosch unit)

 

they will probably last just as long, as long as it's not made from china.

 

the hx uses a special more expensive sensor

 

oh yeah, forgot about that, the hx is the bastard of exhausts.
