Hi I want to add a air intake preferably a cold air intake to my 2009 1.4 seat ibiza but I've ran into an issue find a kit for it having the air box at the back. I've been looking for a one that would require the least amount of moving parts like the battery to fit one in if possible and was wondering if anyone has any suggestions on where to get one or what I can do to make one since I've never made one before.
