how do people gut thier tpi air lid would like to do this

 

I belive you can gut the MAF and the airbox, not the lid.

 

you can cut the plastic baffles out from below the air filters to allow more airflow, remove some of the plastic material inside the plastic Y thingy, particularly just forward of the connection to the maf sensor. mine had a small ridge in there, i cut it out and filled the hole to make it a smooth transition into the 3" maf sensor.

to gut the maf you remove the screens and use a hack saw to cut the fins off.

i was worried about the lack of fins not allowing the unit to cool properly so i left one on there for the heck of it

 

Just cut everything out in the airbox until you see daylight at the bottom.
