Owner reviews for 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.

K&N air filter

i have it in my 2002 passat gls and seems to be working fine so far for 500miles. I guess it does help gas milage a bit from what i've seen so far and helps a bit when carrying maximum passengers (5) in the vehicle cause i need all the torque i can get. Every little bit counts

I had my K&N drop-in installed around 5,000 miles ago by a local, independent VW mechanic. Works great. No idea whether or not there's more power, just care that I don't have to keep buying and tossing paper ones.

I've run K&N's in my carS for over 20 years including 5 VW's and Audi's and NEVER had a MAF failure until the one on my TT recently. HMMM. My A4 1.8T has had a K&N in it for 45k+ and it's running fine. No doubt if you don't oil the K&N correctly and submerge it in oil you will run into problems.

HKS SMF: No oil needed, no maf problem what so ever. Loss of power=1-5 hp.. Do I care, not really... Does the turbo sound sweeter=you bet your ass=lots more fun to drive and listen too. Worth it...totally.

10,000 mls plus, no problems. Performance? Hm, maybe a bit since I'm chipped.

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.

We also had a K&N filter in the car and the Mass Air Flow sensor failed about 14,000 miles later. The dealer did replace the MAF under warranty and did not suggest the failure was caused by the K&N.

I installed per instructions a K&N air filter to my 2000 VW Passat. Upon Driving the first 3 hours after installation my check engine light illuminated and a warning message appeared on my trip computer stating "Emissions Workshop!" VW stated that the error was a result of a faulty air mass sensor. It was determined by VW that Oil from the K&N filter had fouled the sensor and the sensor could not be cleaned. I now wish that I had not installed your product at all, because now at this point I am screwed. I am also out $579.41 for less than 3 hours of use of your product.
