After 220,000 km in my 2006 Touran 1.9 TDI with NO problems, and noticably better acceleration and less Diesel consumption 6.2L/l00KM, I installed the same filter in our 2011 Tiguan 140CRD Diesel. We now have 36.000 KM on that car, and the turbo is faster, because the KN 33-2865 reduces intake air drag by 2/3. Needless to say, a KN filter will make the turbos last longer because of the reduced intake pressure loss<br /><br /> Both of my previous PASSAT DIESELS had more than 330,000KM in 5 years of company car stress, and we never had trouble with the turbos AND NEVER NEEDED NEW AIR FILTERS<br /><br /> KN rated for us: AAA, what more can I say.

I have used K&N filters in every car I have owned for the past 20 years or so. I gave one to my grandson for his Volvo. He liked it so much he asked me to get him one for his VW. He is 18 and in college. He will no doubt be purchasing a K&N filter for every car he will ever own.

It fit in the compartment just fine. My only concern was that the original filter was 3 thick & the K&N less than 1. I was concerned that the change in air flow & excess room in the air duct would be a concern. It hasn't changed anything.
