hey i just wanted to share an issue i had with the header install. i was throwing the PO135 code (bad 1st bank 02 sensor) so i swapped the oem one out for a new Bosch right? well Bosch's website lists 4 (2 oe style and 2universal upstream/downstream) BUT Napa, autozone, etc. didnt even have those Bosch specific part numbers. they each listed different ones. and the different p/n's were actual Bosch part numbers as well. to top it off, they had 2 different bosch part numbers for the upstream sensor (13007 & 15710). here is the weirdest part. when napa/autozone put in all my info they both cameup with 2 different oem style upstream Bosch sensors and they were referenced as such:
1996 civic EX VTEC: 15710
1996 civic EX VTECE: 13007
the correct one for my car which was manufactered 3/1996 is the 13007. i bough on their reccommendation the OTHER one and it kep throwing the same code: PO135. so i switched out to the "E" p/n and BAM all is good.
it was a pain in the ass but i hope no one has to go through this as well. of course if you buy another brand other than bosch this may have been a mute point anyways, but they make good s**t.
