has anyone found an alternative post cat O2 sensor (besides the universals)
i ordered the 16109 from amazon (the one that you just have to trim the nub off of) looking for a similar setup for the post cat sensor.
there's been some discussion about a universal or other spliced in variants creating resistance from the splice and decreasing fuel efficiency.
and quality seems VERY good<ul><li><a href="http://www.ngk.com/default.asp">NGK.com</a></li></ul>
However, if you'd rather not splice then that's your prerogative, and there's nothing wrong with that
