Air filter K&N or Wix

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

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.

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.

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

K&N filters let in too much dirt when they get older & after a few washes following instructions you can see right through them. Then when oiled, dust plugs them up very fast. When over oiled, the oil can destroy the MAF. All in all not worth the $60 for a panel.

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.
