Dude, to sum it up, I'm (and apparently a couple of others here) basically telling you to stay away from K&N in this weather/condition. If you really want a pod get a dry type.
I've had cars revving past 8k with a pod bolted straight to a snail so what's your point? House it in an intake box if it's too loud for you. And yes, there is plenty of room to work with - I'll fit it for you if you need.
If you haven't caught on Evolve actually is a workshop. Check them out in Al Quoz. They will be able to sort out your intake box/heat shield/ducting needs 🙂 - Free plug.
I'm not referring to sacrificing HP for a K&N - they just aren't suitable here unless you are planning on running without your AFM. Simple as that.
We are only trying to offer sound advice so you don't cock up your car. Bottom line, its your car and you are free to do with it as you wish. Goodluck.
