Oh, btw all.
On my 335i sedan with v1.4 on 91 Octane, on stock air filter with 2200 miles on the odo it dynoed:
313.8 rwhp
358.7 rwtq

Then I dropped in some race gas to make 93 Octane mix, rolled the car on the rollers for only about 2 minutes and dynoed and got:
325.34 rwhp
366.11 rwtq

With my sedan I think it would of been a couple higher with a bit more adaptation time (so say 328 rwhp and 368 rwtq).
But with my sedan it was 75 degrees out during the test.
With my coupe it was like 58 degrees out.

They were also on two different dynojets.

But you can see, these two dynojets are pretty consistent.

I think my Coupe makes a bit more hp, but again my sedan was on v1.4 (not v1.47 like the coupe) and it was also cooler when I dynoed the coupe.

But what really got me again was the fact that the K&N drop in filters REALLY do give you a bit more power and for $60 bucks are worth it.
