Since NGK has discontinued the 23151 for 1997-1999 4.0 Upstream sensor, has anyone found a good replacement for this? I can not find one in stock anywhere.
I just purchased a 23131 as eBay states its the same thing, but I will report back if there are any issues.
This site is pretty random, but they carry dodge/chrysler parts. They have the 23151 in stock...according to their site.
