No angst here, but if your air filter (on any car) is a flow restriction, a better flowing air filter will increase performance.

And it goes on to say...

This is equivalent to 0.072 psi or very nearly nothing. The air filter posses very little restriction at all in this application. As long as an air filter is properly sized for an application, the lost airflow will be very minimal. This means that there is very little if any power to be found from removing the air filter, much less changing the filter type. The K&N did flow better than the Napa Gold in the first test to the tune of 0.02 psi. That is less than 1/3rd the loss in the factory piping, and it is a whopping 0.14% of atmospheric pressure (14.7 psi). If you need the 0.14% better airflow, than the K&N is hands down the best filter.
