Worked for 96 Dakota 3.9 V6
My 96 Dakota was running very poorly and the engine code said this O2 sensor was the issue. Changed it out and it ran great after that. Highly recommend you start a few days early applying PB blaster because these can really become seized in the bung.

Only time will tell!!
Perfect fit for a 1998 Jeep Cherokee, best thing I can tell everyone is to prelube it the night before, and when it breaks loose give it another shot of what you think is the best penatating lube. And it will make it alot easier coming out. So far so good works like its supposed too.
