Oxygen sensor replacement: what type?

Headache · Mar 25, 2004

I did a search on the forum, but couldn't find an answer.
I own a '91 XJ 4.0 and what to replace the oxygen sensor. As I have read, Bosch is a common replacement but what type exactly should I buy??

Thanks in advance,
Headache

I recently replaced the O2 sensor in my '92 4.0. I got mine at the dealer- a little over 90 bucks with tax. Within a week, I've seen MPG jump up at least 3 to 4 (to about 20, with a good mix of city driving)! Having asked around and looking on the 'net, the consensus is original equipment.

Thanks, I will make sure that I get an original one. Indeed, I am doing this too to increase the MPG. Mine is about 12 now..

I'm way too cheap to buy a dealer o2 sensor. Mine works fine and I've been getting 20 MPG hwy. Chrysler doesn't have a o2 sensor factory... they buy one from a manufacturer, mark it up, sell it to the dealership, and the dealership marks it up again and sells it to you at some horribly inflated price. :laugh3:

I replaced mine with Bosch about 3 months ago. Better price.
