Hi, i just currently was working on my friends my GTI and i intalled a new intake for his car and we decided to buy this ducting tube and kind of do a DIY type of air ducting to increase the air flow to his intake. So we connected it to his modifice intake and rand it down to the bumper. has anyone tried doing this to their E46. I noticed there is a whole under where the ecis cai is, and i was wondering if anyones tried puting some ducting tube from there to the bumper or something, to increase the amound of cold air to the intake?
