before i got my car i was used to having my I6 powered 300E. having six cylinders was great and i could maintain 90mph for hours on end. i just went from southern CA to the bay area a couple days ago. the 1.8T did great! did much better than expected. i had just had my 15k service the day before i left too. stock air filter was in because i forgot to put the K&N back in. when i got back though i saw how much dust was on the stock filter after the trip so i was glad to save the K&N. anyway back on track, would have been nice to have 6 cylinders on the open road but the 1.8T was great. i kept it at 80-85mph the whole time. 6+hrs.

Pros: 1.8T did great

Mileage: 15000 km

Never a problem with my K&N dropin, it was rather "dry" when installing it. Performance gain? Honestly, don't know..., seems my butt dyno feels a little more free breathing.

Pros: no problems, feels more free breathing

Cons: uncertain performance gain

Vehicle: Audi A6

I had my k&n installed on my passat at 19k miles, i have had no problems but was warned when i purchased it to not put too much oil on it when you clean it as to not @!#@! up the MAF. I haven't noticed a performance gain with the K&N, however when the stock one was put back in i noticed how quiet my engine was when reving hard. I don't like it at all so im putting in another k&n(i like the noise)

Pros: no problems, preferred engine noise

Cons: no performance gain, requires careful oiling

Vehicle: Volkswagen Passat

Mileage: 19000 km

I've had the K&N in my V6 for the last 50,000 miles without any problems. When it came time to clean it I let it dry thoroughly (over 24 hours) before oiling, lightly oiled it, and let it soak in thoroughly before installing.

Pros: no problems, good longevity

Cons: requires careful cleaning/oiling

Vehicle: Volkswagen Passat

Mileage: 50000 km

I have had a K&N in my 1999 Passat for over 20,000 miles. No CEL's or any other problems. I didn't notice any siginificant performance gains, possibly a 1 mpg increase in gas mileage. To be safe, I haven't put a K&N in my 2001.

Pros: no CELs, no problems, slight gas mileage increase

Cons: no significant performance gains, potential incompatibility with newer models

Vehicle: Volkswagen Passat

Mileage: 20000 km

i had the same problem when i fitted a K&N filter on my 2000 Jetta, I probably overoiled that thing and it clogged my MAF. I didnt notice any gains maybe its just all hype but I will not use a K&N filter on my Passat.

Cons: clogged MAF, no performance gains

Vehicle: Volkswagen Jetta

I have a K&N in my BMW and it has helped with fuel consumption - however - it was a pro install and has a cold air duct fitted to the front grille. The car was then also dyno tuned to optimise the better airflow. However - I take the benefit in fewer filter changes and better fuel consumption.

Pros: improved fuel consumption, fewer filter changes

Cons: requires pro install, needs dyno tuning
