before i begin, i'm doing a custom turbo kit on my b16a2.. when i install the custom pipe that goes to intake mani... what should i do with the air sensor, (the one that goes in a cold air intake) should i make a hole for this sensor in my custom piping.. or should i just leave it out?? and what are the affects of leaving it out..

 

Its the AIT sensor i believe, id put it in your new charge pipe....

 

put it in so u dont get any CELs...

 

can you just use a breather?
