K&N drop in filters
Yeah, I don't know, I'm not feeling anything at all from these, if anything, I think I lost torque??
I made sure I installed it correctly, along with the seals etc. Not that I was expecting power out of drop in filters, but I would think the car would get slightly louder during WOT.
I should have just gotten the stocks.

Not for nothin' but make sure you didn't over oil the K&N's and get a small amount on the MAF sensor. In my past experience with those filters on 'vette TPI motors and others the big advantage is the "lifetime" filter deal. When they get dirty you just clean them and re-oil.

On my w203 I haven't fitted a K and N but have updated the stock more regularly (they get very dirty) and frankly I reckon I feel a bigger difference by fitting a new stock one than a "sport" filter.
Maybe MB designed the stock one better than we think!
