Air Tube hook-up on headers
I see several different headers offered with or without this provision .What does this plumbing do anyway. I read where guys just pull all that off and plug holes and throw it away.I am trying to purchase headers and am finding that the ones without the air tubes seem to be more plentiful than the ones with. What are the draw backs of not hooking up the system and what codes could one expect to get. Thanks for any explanation ,My car is stored for winter months so it gives me time to think of this stuff .Thanks again for any help

The plus side is that after you get rid of all the air pump plumbing you will be able to change plugs so much easier it's almost unbelievable. Also, almost every brand header there is blows the header air tube pipe off after awhile and you have to weld a patch over the hole.

The above statement is true however,,,,, the PCM turns the AIR Pump on during specifing driving conditions to pump air into the exhaust system to test the AIR system. If the PCM doesnt see the expected changes in O2 sensor readings it will set one or more of three AIR System DTC. The AIR system is part of youe emissions system. If those DTCs are set, you will never pass an emissions test. You can have the function tuned out.

This isn't a good way to go if you have to face smog police that look under the hood.
