Everything is stock. I did a Search and looks like it could be a Vac. line. I will have to look closer since I did have the air box off to try to clean the MAF. I sprayed it with MAF cleaner while it was still screwed in cause I didn't have the safety torx but I could see the wires, would that have ruined it?
