Hi, haven't posted for a while
Here are my questions on 2007 650i E64.
Recommendation regarding a new air filter, OEM part is 13 71 7 521 023
Is it worth while to buy a higher performance air filter
in terms of gas milage and performance
Any suggestions.

Same question on cabin air filter OEM Part number 64 31 9 171 858
will the cheaper non-OEM models work/fit just as good.

I only have one smart key fob. the other key along with spare key was lost by previous owner
I know I can buy an uncut spare key part number 51 21 7 057 672
Then have it cut at a locksmith.
My question is if buy this spare key, have it cut and insert into the plastic spare key fob that is in the glove compartment, will I be able to open and start the car.

Final question. has anyone managed to pair a samsung android phone with a 2007 BMW (hopefully a 650). I can't get the two year old samsung to pair but can get 5 year old iPhone to work just fine.

I will answer the one I know for sure...

A cheap source for Mann cabin filters are www.autohausaz.com. They have both the regular and carbon activated. A side note, you need to buy two of them since you have cabin fresh air intakes both left and right.
