My 98 CRV has 135000 miles and still has the original O2 sensors. I have not had a check engine light go off, nor have any codes been retrieved showing a bad O2 sensor. The car runs fine (idle, fuel economy, etc) so I wonder if its worth replacing them. Are there alternatives to other than buying directly through Honda? Do any auto-part chain stores sell replacements?

thanks

If it ain't broke don't fix it !, The service manual say's 110k... Many folks have had success with Bosch O2 sensors but their only a few bucks cheaper... I'd go with the Honda's. You can find them cheaper on-line rather than the dealer.

Go to the NGK website & look up the sensor you need... (they are stock honda)

...and order it at Summit Racing...cheapest I could find...
