I lost power on the dyno using K&N filters so returned them and picked up BMC filters.
I think I actually paid less for the BMC filters due to a pricing mistake on Amazon too
Not had a chance to compare the BMC filters against stock on the dyno yet, but they sure sound nice.

It certainly doesn't feel like I have lost any power (though nor did I notice the ~7-10hp loss with the K&N).
Build quality is fairly similar, though the ones from K&N were absolutely soaked in oil so had to get some of that off before putting them anywhere near my car.
