i think it's a good investment if you're not planning to get a CAI
soon...and i mean soon. lol, i bought a K and N and i loved it...right about the time i got an Intake
...1.5 months after!! ha,ha,ha..i could've saved 40-50 bucks on mtecs, or some other mods. but i was pretty ignorant back then (well more ignorant then than now...lol) and had i kown i would have held off on getting a drop in. but if that is what you are going to use for a while then it is a good investment because k&n specializes on that and they last forever!
just my one cent...i'm keeping the other cent for my mods budget
