Reviews of K&N air filter

I ordered two of the K&N filters for my V8 T-Reg (hey, anything to improve mileage). I've installed these things on my previous car before and it was pretty cake.

K&N air filter

Plugs, Coils, Maf, Front 02 sensor have been changed, I am not running motor mounts of any kind, my car feels so Unsmooth compared to other 1.8t´s I have driven this only seems to happen under low load... you can feel the cabin vibrate... not a lot but defenetely the steering wheel, pedals, shift knob. and the car seems to stop and let go, stop and let go (jerky) whenever I let go off the gas pedal in gear... it feels so unsmooth!!!

It's not the worst mod actually, but I got ripped off by the ppl who sold it to me (I paid nearly $90 with tax) because I didn't know how much it was worth... no gains whatsoever and that's what upset me. However, I did forget that I won't have to pay for another air filter for the rest of my life, so it's not so bad after all

Basically...modest if any gains involved with going with a straight drop in.....the only real benefit IMO....is that for the $60 air filter...you never have to buy another one again...that's the main benefit as far as I'm concerned.

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.

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.

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