just installed a K&N drop in filter
Optimize the fuel trims (A/F), set appropriate timing advance (vehicle to vehicle difference), raise fuel cut, raise speed limiter, etc. Basically a reprogram of the cars ECU. It makes a HUGE difference in the car, even without any mods. As soon as you start modding heavily you'll NEED some sort of tunning; either tuning the stock ECU or adding and aftermarket ECU.
Hope that helps.

Like they say every car is different, my Evo definately feels faster and you could really feel it once the turbo kicks in. My gf had no idea I purchased the K&N but when she got in she already knew my car sounded a bit different. Overall I am happy with it 
Any idea how much hp gain with just a drop in?

I got the K&N drop in and took the airbox cover off then wrapped wire around the top like a square so the airbox brackets will hold the filter in. You can hear the turbo much better and the BOV. I've had it like this for 3 months now with no problems. If you really like the turbo sound and wanna hear your stock BOV its a good mod with the drop in filter.

I've got a K&N too

I decided to go this route so i don't need to change out an aftermarket air filter everytime i go to dealer for warranty or free maintenance stuff.
not to hijack the thread, but i've got a k&n drop in filter that has about 1000 miles on it that I'm looking to sell if anyone is interested, i bought it from a friend who had it on his car for about 600 miles and then i had it on mine for about 400 and then i got the hks rs intake..anyone interested?

A K&N drop in filter is simply a higher flowing cotton gauze filter that replaces the paper one that comes stock on the Evo.
K&N also has a complete intake system similar to the AEM, but that's not what they were talking about on this thread.
