So when I lift the cover there should have been one under my filter. Nope just replaced it today. But I have heard some guys are removing the one on the back of the cover that is friction welded on. Is it advised to remove this one?

I read a thread about how removing the charcoal filter will give me a boost in horsepower and was really skeptical. I mean c'mon, people pay thousands of dollars for things that give them a modest boost and here was something that's free, takes like 5 minutes and is supposed to work. I thought about it but did nothing. Fast forward to last Saturday night. I was enjoying a lovely dinner with my family at Arthur's Tavern in Morris Plains, NJ. There was a chap sitting next to us with a BMW Technical Support Team logo polo shirt on and I struck up a conversation. Seems this gentleman travels around the country training BMW techs on the nuances of servicing our cars. After a few minutes I asked him his professional opinion on charcoal filter removal and if it really did anything to improve HP. He leaned back in his chair, smiled and said "you just found out about that?" Then he laughed. His wife even laughed. I laughed. My kids laughed. We all laughed. Hmmmm, it seems that the charcoal filter removal thing is real so the next day I tried it. For those of you who have 545s or 550s and are unsure, there is a HUGE difference in performance. When I nail the gas peddle the car literally leaps forward, pinning me in my seat. It also makes the coolest, most pissed off growl that I have ever heard while doing so. As for you, my E60.net friends, I am sorry that I ever doubted you.

If you don't remove those clips you run the risk of one working its way off and making its way down the rest of the air intake. A half-inch wide piece of metal flying off and into the engine isn't a problem you want to have.
Don't let that scare you. It is very easy to do and has great results!
