Here is a 2.0 owner with a 1999 GL and 56K on the clock. I decided to use K&N drop in filter as a replacement on the CAI. So here is what I noticed after I put K&N on my puny 2.0: 1. 1.7 - 2.3 EXTRA mpg 2. Better throtle reponse, especially above 3K rpms 3. No problems concerning the MAF and oil flying off the filter I think my $45.87 was well spent!
Your experience is your experience- that's fine. I have seen gains. My fuel economy has gone up about two miles per gallon on average.
I just turned over 9K on my car. installed a K&N on the day I got the car with 34 miles on the clock. After reading your post the other day on this subject, I decided to check my MAF and intake for signs of mineral oil. There were no signs of it. Not on this car, or the Jetta 1.8T I had before this one. I ran that car with a K&N panel filter for for approx. 36,000 miles until I sold it for the GTI. I have owned (6) cars in my life. (4) of them had K&N filters in them. I have never had a problem with any of them as a result of these filters.
Agreed ^^ I did mine a wek ago and the sound is great! The DV is definately audible now and the turbo spools a little quicker and whines louder! You'll get a little better mileage like alreadt stated and I'm sure you'll gain a few HP, but its not very noticeable.
The K&N drop in is nice. I don't want to do a CAI, so it's a good compromise. I don't know if there is much perfomance gains, the 1.8T feels a little stronger with the drop in filter. The sound is great though. I put my new filter in last weekend and took a friend out and he was loving the sound of the turbo and DV coming through the stock air box. Nothing too crazy like a CAI or BOV, but it definetly makes alittle more noise.
K&N Air Filter
I did. Driver's side <2 minutes; passenger side required a plasma donation. Very, very tight fit. More induction song now, but the regular paper filters are so big I doubt that limited air flow is a problem.
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.
Many manufaturers, including VW, Ford, BMW etc. have determined that the oil used to assist the paper gauze as a filtering medium is contaminating the MAF sensors. When contaminated, replacement is required as MAF sensors cannot be cleaned. Apparently, Ford has already issued a TSB on this, and I understand VW/AUdi is just about to. Anyway, most Dealer Service depts are now very much aware of this, so it's unlikely they'll cover a contaminated MAF under warranty.
I had a K & N put in my 2000 Passat and same thing happened to me. Turned off car and next time I started it, I got the check engine light.
