K&N drop in filter VS Open faced or CAI style

[SR20drftSX]

which one would be better , id like to just buy a K&N drop in filter and keep my stock airbox (its already cut , whole bottom is off and whole filter is exposed to air)_____

or would yu guys suggest getting a ram air or CAI style filter? whats the advantage?

thanks

Go CAI.

Nothing to be gained by cutting the airbox open, you're sucking hot air.

Why K&N, may I ask?

i was suggesting K&N i guess because they are the only ones i know of that makes a drop in mesh style air filter with the metal rib type filter, and i dont want a CAI cus i think itd get dirty being near the ground and idk if i can afford it..any suggestions?
