K&N Air Filter. Improved MPG?

2760 Views 5 Replies 4 Participants Last post by  KonradL
Thinking of tossing a K&N Air Filter(s?) in the car, was wondering if anyone's had this done and if so, any improvements in anything or is it just a pointless mod. I had 'em on my last cars, and the main improvement was not having to ever have it replaced. Not sure if MB makes a good Air Filter from the Factory though.

Take a look on Ebay, there's a guy from NY that has the K&Ns for about $38 each, that's what I was going to do, but I read a lot of comments on how they can screw up the MAF because of the oil that's applied on to them. Instead I went and got Mann filters.
If you get them, let us know what you think.
