RE: K&N air filter for e300td
Hmmmm, how does any automobile get "more air than it needs?" Is it hyperventilating[8)]
Seriously, any car gets everything it needs until the size of the runners, the diameter, the length, etc limit any additional intake. It's all controlled by the throtle body and measured by the MAF Sensor -- up to the physical limits of the system. The K&N may nudge upward the physical limits.
If I remember my old intake manifold days, the smaller longer runners favor the bottom end and the short fat ones the top end.
When you let a car breathe better, you increase the top end typically.
Make sure you never over-oil the element though. That oil gets "fogged" past the filament of the MAF Sensor it can cause it to fail.
