Rear o2 plugs?
 

I am about to purchase some long tube headers. What do I need to plug the 2 rear o2 bungs? I plan on getting the rear o2's tuned out.

Does a sponsor sell a plug or do I just need to pick up something from a hardware store?

summit has the plugs for like $4-$8 depending if you want stainless. they are 18mm 1.50 plugs. I had to order from them because no one has metric shit that size in my town. hope this helps

many people just leave the old o2 sensors in there to plug the holes....that's what i'll be doing.
