I need some opinions on the K&N Performance Air Filter.
 

Is it worth it to pay double the price for performace air filter? I understand that they are usable and such, but is it worth the money or should I just stick with the basic air filter?


Also, Mobil 1 OW40 Synthetic good choice for a 2000 A6 2.7t?

use the regular.
 

I had a K+N and its not worth it to clean and oil it.

the Motor oil is fine
 

The K&N Lube oil in the air filter is not.



it can get into the system (MAF) and "kill" it

Oil = good...........air filter = waste of money

It is a physical fact that you cannot filter air without introducing some form.....
 

of restriction in flow. Therefore if you have a filter which flows more air for the same given surface area, it will not filter as well - your choice.

This is ignoring the fact or fiction behind the possible problems caused to the MAF sensor which is not designed to be dombarded with micro-droplets of oil from time to time - it is designed to work in clean, dry air, which has passed through a paper filter - again, your choice.

I ran tests with and w/o K&N. No change in measured airflow a chipped 2.7t.
 

The airbox/air filter is not a point of restriction on the 2.7t. Save your money... just use a regular filter.

M1. Good choice.

I doubt anyone here would encourage you to buy anything other than paper.
 

STFA for MAF.

They tend to screw up the MAF sensors because of the oil on the filter.

skip....the oil is fine, been using it in the big girl forever

shhhhh - don't confuse people with actual measurable facts!
