  I'd recommend against the K/N O2 bungs.  I bought two, drove my Mustang
to the muffler shop and asked him to weld them in.  He used a torch to 
burn the hole, then arc welded them in.  He had a bear of a time with them.
At first he thought there was a coating on my headers, but I told him they
were nothing special.  Then, when he tried to get the O2 that use used to
locate them out, it was very tough to get out.  He got the first one set up
and working (by using a tap), then he pulled a Perfection one off his shelf.  
It went in with no troubles.  He figured it was inferior metal used on the K/N 
unit, but they both cost about $10.00.  So, I'd recommend you just hit the muffler 
shop and ask them to weld them in and get them from the same shop, or get the same 
brand they use.  Perfection should be sold by most parts stores.
