I'm also interested in this...I've read a few negative/positive things re:cold air intakes (i.e. BMS) increasing power due to higher air flow, but also some negatives with heat soak (due to the intake being right next to the turbo) and also MAF damage (oil...which also affects the K&N filters).

Couldn't find any hard conclusive data one way or another. What have you guys experienced?
