So I was curious and just took this filter out on my 545i... it does growl but its hard to tell if its louder or not. I do think there is a slight increase in power, but no "HOLY CRAP!" moment. Time will tell on the gas mileage. It certainly cant hurt taking the filter out (extra restriction) - the engine will breathe a bit easier - more air is a good thing.

I took mine out today and noticed a tiny difference in throttle response. I have a service appointment with Dinan next Friday and was going to get there opinion. I will report back with any findings...

why not remove the regular filter as well (further less restriction) and just put a coffee filter at the end of intake pipe just before MAF?

I'm gonna leave mine in but I will compensate for it with one of these: http://www.electricsupercharger.com/
Imagine what one entire PSI of boost will do for my performance!

I have had mine out for a few weeks now and there is definitely a difference in hp and rumble... gas mileage has increased by almost 2 mpg and I dont baby my car driving almost 100 miles per day with a good mix of "D" and "DS"...

Mine has metal clips on the top side that you cant see... i pried it away from the top with a thin flat screwdriver and it popped the tension on the clips.

I have an 05 545i and pulled it out yesterday. I didn't notice any change in sound and can't say I notice any power increase. I'll leave it out since it doesn't harm anything to see if I notice other gains.
