I would only consider doing this if it offers a massive sound improvement which is only attainable from a cone style filter.
I had a Dinan intake on my F85 X5M and it was a sealed design. I got zero sound improvement. Did it offer any hp gains? maybe maybe not. When you have over 560hp you aren't going to notice such minor hp increase.

I hear you.... and agree. A K&N isn't going to net "huge" HP gains by any means.
My biggest motivation...... is dynotuning. My appointment is this Saturday. The last X5M50i that they tuned ended up with a 150hp increase, and a 100nM increase..... I had hoped that "maybe" the K&N would give me "just enough" to inch over the last guy.
Still..... going to be a huge gain. Very excited about it nevertheless. But from now on, I'll always wonder "I wonder if I'd had the K&Ns installed, if I would have had 10 more?"
