I know other people on these forums have run it for longer. I don't think it pulls any harder (at first i thought it did and maybe I've gotten used to it).

when i first did this, my car did have a deeper sound at first, but I think the ecu took note of this and regulated the amount of fuel that it needs to inject with the new air flow coming into the engine. Now my car sounds as it did stock IMO. There isn't much change in the higher RPMs but you can hear something different if you have a keen ear for it.

The only thing I wish I had was a euro box since it would be much easier to take out and clean the filter when I need to. Other than that, do as you please. Paper or not, I haven't been convinced to buy an aftermarket intake (unless i could afford gruppe M cause they sound beautiful =P).
WOW so let me get this straight, you have driven your car for 6k miles with the K&N filter and experienced no problems? Thanks for sharing. Well I don't know about anyone else, but that's good enough for me! I mean if that doesn't qualify as an engineering study I don't know what does. I mean heck, what's wrong with a little extra dirt getting into your engine, right! It certainly sounds like a worth while modification in order to get a little extra engine sound.
