header o2 installation problem July 04, 2008, 01:47:47 PM okay so i recently got a set of stock ford ho headers off a 89 mark vii and i was just getting ready to put them on and i realized that the stock manifolds have o2 sensors in each side, and the headers do not have any place for them to go. so is there any easy way to go about installing them, or can i not use them or what?

header o2 installation problem Reply #4 – July 04, 2008, 07:36:52 PM i am thinking about getting an x pipe for the car now, but if i do that will the stock ho headers hold me back on power over aftermarket headers? if they will, then i may just sell them on ebay or something and just pick up a pair of mustang bbk or mac headers or something Quote Selected
