Title: Unsuitable replacement for 2005 Audi TT
Review: I purchased this filter because the Bosch Website listed it as the replacement for a 2005 Audi TT Quattro 1.8L. Size-wise it's spot on, but the OEM Audi filter has notches around it and pockets on the ends so that it mates with the part that holds the filter. So, I had to pull out the scissors and do some crafting, worried the entire time about cutting a hole into the filter. After some trial and error trimming, I managed to get the part in, and it's working fine. However, I expected a part that really would just slap right in; I plan on buying a genuine VW/Audi part next time around.
