Yes, the K&N drop in.

Only 2K and yes it is possible. However, I've run K&N's in my last three vehicles and had similar results. Both in F/I and N/A.

Believe me, if it was really that easy to get more mileage, extra power and/or torque, don't you think that the Honda engineers would have considered using a free-flow air filter such as the K & N from day-1? 
As I posted some time ago on this subject, we had dyno-tested a club-member's Porsche V-8 with and without the K & N. The results were a negligible 2 H.P. gain @ 5500 rpm; hardly what K & N advertised.  |
I kinda figured that this would turn in to a hyperbolic theorem and that was not what I was going for...take my word or not. A good indicator of a change at the MAF is the fact that it took about 5 minutes to smooth out the idle immediately after replacing the filter. It is simply a free flow filter. I've logged over 100,000 miles with them in different cars, so forget about all of the what if's...as long as you maintain them properly. I don't want to sound arrogant here, but there are just some things you know from doing it long enough.
