What is it and where does it go? Could the absence of it be the cause of my car becoming very hot and being laggy (not accelerating smoothly)?
This came off while getting HIDs and fogs installed. Right after I got a CEL; this is probably not the cause of it but I'd like to put it back on and check.
UPDATE: I resetted the ECU and the CEL went away. I haven't driven it yet but the car still sounds much louder (like if you remove the tube going to the air box resonator).
