I needed the computer to stop throwing codes so i could pass MA inspection. the last code i couldnt get rid of was P0410, the A.I.R. System, because i bought the car with an OBX header on it and it doesnt have to grove in the back to allow the air pump to work properly on the third gen.
Solution, modify the header flange.

I love owning a machine shop

Some high temp silicone hose and we are good to go. No it hasn't melted yet and i have taken it on a few 60+ mile trips.
