Air filter K&N or Fram

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 bought the K&N at http://www.martelbrothers.com/customer/knstore.php . It is cheaper about $41 each. I called VW serviceman to make an appointment that I would like to install K&N filters, and he told me anytime.

It's winter in Toronto and it's about -10 outside.. and i just put in a VR conversion... new Sparkplugs new wires new K&N Filter Neuspeed Chip Air Filter Oil just changed New G11 Coolant. anyway i keep checking the MFA and the oil temp is consistently in the 100-118 Celcius range.. during traffic or cruising around the streets its at 96-100 and when im going good on the Hiways at around 100-118

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.
