The last time I priced an OEM O2 sensor from Manchester Honda (for a 1st-gen CRX) it cost 178USD. The Bosch ran me $20. There's no way an OEM is going to last 9 times than a Bosch universal.

Here are some tips on R&R. Take some cutting pliers and destroy the body of the sensor such that what's left is short enough to fit inside a deep well 7/8" socket. Some replacement sensors are short enough to fit in the same socket, some aren't. I would suggest trying very hard to source a short one. You can tuck the wire up into the socket and install it that way. If you decide to use anti-seize compound on the threads of the new sensor be certain to keep the sensor tip itself dry. You will ruin the sensor if you don't. -scott
