94 Intrepid 3.5L - NAPA Echlin O2 sensor superceded by Bosch

No, the Bosch part is not OK, unless you want to do the job again (and again, and again) in short order. You can still get Echlin O2 sensors from NAPA, you just have to specifically ask for them. The application info is in the NAPA Echlin application book, which means the counterman may have to get up off his tush, away from the computer, and actually open the book. Or you can save him the hassle and tell him to order you an Echlin OS308.

Chrysler dealer will sell you a good one at a high price. It will probably be an NTK, which you can buy less expensively (P/N 23023) from

Thanks.

Are the NTK spark plugs (7252) OK?

NGK (spark plugs) and NTK (O2 sensors), same company. I like NGK plugs.

Daniel - I've taken to heart your comments in the past about Bosch O2 sensors not doing well in Chrysler products in general. However, I'm pretty sure I've seen posts on LH forums (from people that should know) that the LH cars came from the factory with Bosch O2 sensors (and they don't seem to be a problem until close to 100k miles (judging from the same forums) - in fact my Concorde still has the original sensors and runs fime and gets good gas mileage. How can that be?

Bosch OEM O2 sensors are not the same as the aftermarket ones.

Bill you are correct, they have been using Bosch 02 sensors for awhile now, I dont think Chrysler makes there 02 sensors.

But the "OEM" Bosch part is apperently not at all the same as the aftermarket branded Bosch part. Bosch's operations for OEM and aftermarket apparently don't have very much to do with each other.
