Autotech Cold Air Intake

I was wondering if anyone has installed an Autotech cold air intake on their Jetta III and know how well it works and what it sounds like?

Well I bought the intake and love it. It is the cheapest and one of the best CAI's for Jettas. My only issues are thath the instructions were confusing and did not include pictures. After calling the first time I was only more confused but I was able to get the needed help after the second call. My reason for difficulty was that my car is not equipped with a factory air pump and the directions were not very descriptive in describing what went to what. Overall though I would reccommend this intake.
