I got a Hengst Oil filter and two Mann Oil filters. I prefer to use K&N Oil filters. Right now I'm using a Fram.
Pros: prefers K&N Oil filters
A K & n oil filter is a good filter 2 use. I work at a car dealership and checking out the quality the k&n vs oem, the k&n is a better filter. I usually use them or mobile one on my car.
Pros: good filter, better quality
about 35 mpg freeway & about 27 city/freeway daily driver '89 Jetta 4 door 1.8L originally (bored .020 over) on digi2 with a K&N air filter I'm running nothing but 91-92 octane chevron/shell gasoline.
Pros: 35 mpg freeway
Cons: 27 mpg city/freeway
Vehicle:
Volkswagen Jetta
I use a K & N passat filter. Its the same (I think) you get the added oil capacity.
Pros: added oil capacity
Vehicle:
Volkswagen Jetta
I use K&N, just because my local discount always has it in stock.
Pros: always in stock
I have had K&Ns on my last 3 diesels and 2 gas engined cars and they all ran over 300,000km. There is absolutely no evidence of fouling of the MAF, but there was a noticeable increase in power and mileage on each car and the intake track is noticeably cleaner.
Pros: increase in power, cleaner intake
Mileage: 300000 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 use a k&n and I've noticed some grit mixed in with the oil that coats the walls of my intake track. I only clean it every 40k though.
Cons: grit in intake track
Vehicle:
Volkswagen
Mileage: 64374 km
My vr6 had nothing but maf issues after I installed a k&n. I wouldn't even dream of putting a k&n in my 1.8t. The paper filters are fine. It's been proven on the dyno more than once that you get no gains from a k&n whatsoever. Unless you think you are going to clean and reoil your k&n to reuse it and save on filter costs (in which case again you have to be careful not to over oil or you screw up your maf up big time) there is no specific benefit to gain by installing one. Let me note that I've not noticed the same issues in older vw's, just mk IV's.
Cons: MAF issues, no performance gains
Vehicle:
Volkswagen
