Fitted drop in K&N to my 130i. Definite improvement in response. Feels like it should dyno a few horses more.

Usually it will improve response and some gain on the Torque at certain band of the rpm. Due to the nature of measurement variation in the dyno, you will not see any great change in hp if the variation is like a couple of Nm

I believe those gain numbers posted are their BEST run out of certain number of runs they have tested. They will not post their average for sure....
