Sleeper Mods

I have an 08 135 vert that I'm looking to mod up. I've debadged it, and I'm following the crowd with some VMR CSL Reps....aside from other external visual mods, I'm looking to juice up the performance a little. My utmost concern is warranty disturbance. My plans include a JB2 and an intake. I love the sound of the BMS Dual Cone, as well as the current price, but I'm open to any suggestions. I'm concerned about the possibility of raised oil temp during daily driving, but that's perhaps only a small issue.

Here's my big question: I know that a piggyback or reflash of any kind voids the powertrain warranty (if discovered), but I'm not concerned about that as the JB is invisible and extremely easy to install and uninstall for services. How does BMWNA feel about aftermarket intakes? What would the potential warranty interaction be on one? If there's any chance at all that there would be negative warranty interaction, I'll probably avoid one.
