My Ride: 2004 645 Ci, Individual Stratusgrey Metallic with individual grey leather
Individual Stratos metallic, Shadow line, Black Individual leather, 19'' ellisoid, Panorama sunroof, PDC, Dynamic drive, Adaptive steering, Adaptive headlights, Voice control, Logic 7, Prof sat nav, BT phone, TV, Heated Sport seats, Ski sac, light pakket, CD-changer.
Mods (so far): iPod interface, K&N Airfilter.
Doc has contacted me about this and I have agreed and looking forward to visit the K&N research center after contacting the engineer there to develop the 545i prototype. I must say I am skeptical as I have been in the past about air filters which (also) suck up internal warm ambient air, but will give them a chance to prove it on the dyno with a before and after run.
Will hopefully have some results in November.

As stated, the results on the Dyno are a gain over the whole rpm-range of about 7 HP at the rearwheels(!), but the temp difference on the Dyno was significantly more than during a test on the road. Which means that on the road the gain in HP is even more! But an exact figure is by that means not possible to measure.

well ppl that got the afe intake, got similar if not better numbers... plus the looks with the afe... its a obvious choice.
Than again like you said, its just a prototype...

Actually, the AFE claims to get an increase in RWHP, but it is hard to find evidence e.g. before- and after- Dyno's.
The only evidence I found is: hardly any gain or even a loss!
Click
another click
So, I can't find any proof of similar or even better numbers!?
Apart from the looks, so NO obvious choice.
For reputation, K&N is represented in I think all motorised sports! I have never seen a aFe decal on a racing car or motorcycle!
So I have more thrust in a very professional and dedicated company like K&N than aFe.
It is easy for me to say, because I have been there. They are very serious about developping and testing their new products.
For me, an obvious choice

Different engines will gain different power. At the end of the day if you take off the stock restrictive air box, and whether you slap on a AFE kit, KN FILTER, or a $15 filter off ebay diy thing, you will get increase in numbers regardless. Maybe one filter has better flow over the other, but the extra 1-2 hp i dont think you will notice. Just after doing such a mod, you feel bit more tq. maybe its just a placebo effect

You are probabely right. The little gain in power in our car might be too small to notice.
But knowing the engine is better able to breath, gives me a good feeling
The other thing is the sound, it should be better hiswell.
So, NO disadvantages, just (maybe minor) advantages And another thing, for me it's free!!!
The major thing is that it is just another mod to add to the list.
