Oh yeah, you can feel the difference driving off.

The cones aren't bad, it's the 'filtercharger' oem replacements that i'm talking about.
They are proven to allow more foriegn debris into the motor than a stock filter. If you oil them sufficiently so that it's filtration matches that of an OEM filter, it doesn't flow as well, and it runs the risk of ruining your heated MAF wire.
