Air filter Mann or K&N

Only engine mods is a K&N filter...Highway, I have seen as high as 31mpg.

I also changed spark plugs, oem bosch are not to expensive at any parts place. I changed the air filter to a K&N, I am running motul diff and engine oils now.

Just arrived from ECS, I installed my smoked tail lights on my '08 wagon. Has the Euro version rear fog. When signaling they change from red to amber when blinking, unlike the US version is always red. And the internal housing of the lights that are normally chrome are blacked out. Love'em.

You get a few more MPG and with the windows down you can hear the turbo a little better.

You'd have to have the oil really dripping off the filter for it to get sucked in. K&n have done testing , and they couldnt get oil to come off the K&N even when they over oiled it, and even when they did get oil on maf's they still worked fine

1 new mann air filter 6$

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.

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.

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.

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.
