Accidentally snapped the primary O2 sensor (before the cat) while putting on a new exhaust manifold. Didn't think much of it, as I thought I'd replace it anyway. Called up Honda.... $400!!! What??!! Can't be right. Check Autozone---Bosch unit is like $350.



I looked through several threads and since most aren't familiar with HX's, they'd give links to other O2 sensors which were less than $100. This is a 5-wire specific to HX's. I am guessing I'm going to have to lube up and let Honda go at it. Unless anybody has any other suggestions...

My Civic is a 97 HX 5-speed.
