I purchased this for my 04 VW Jetta GLI 1.8T. Prior to this I just had an aftermarket K&N air filter mounted to the MAF which was ok. Installing this intake was almost as much of a PITA as my 08 CIvic SI but in the end worth the extra grit. There is some relocating, adjusting and pipe movement to get this one piece CAI in there right. Anyways, the brass tax; very noticeable difference, the azzdynoclinometer approves and it sounds good too. MPG is slightly better but not drastically noticeable.
