OK!
I know I'm opening up a can of worms here, but my dad put a cold air intake in his e39 and the throttle response has improved alot. I just finished helping a friend put one in his ricer and his throttle response has improved as well. I would like to know if the K&N air filter that I have in my stock airbox is the best way to go and what other Cold air intake options their are for my 525i! I was looking around and found

That looks like it would just suck in hot air to me, so then I was thinking of makiing my own, but then I searched the forum and found that if you place the air intake too low it might suck up water (kind of a "duh" thing to me). So, what should/can I do if anything? Any suggestions?
Thankx
