KNN drop ins work well.

How about the non CAI knn filter ? The one that goes right in the stock air box instead of the stock paper filter ? Would it lead to HP gains ? Is the oiling really necessary ?
If you experienced again from a CAI. Cool.
What I haven't stated is I have a CAI on my 535i/5.
my 535i/5 is chipped, 24# injectors, custom reso delete exhaust and it has a stock 3.46lsd.
The car came with the CAI when bought.
My previous 535i/5 had a stock box.
The only noticable difference between the 2 was the exhaust note. Any gains I've gotten aren't contributed to the CAI. For my exhaust is more aggressive.
To make this more interesting and current I borrowed a box from a friend who was parting his 535i.
Installed it and ran it in daily situations (stop and go, highway 50-65ish+).
Again the only difference was exhaust note.
Now again if you got better performance out it cool.
Get us some dyno numbers to compare the 2.
For I'm all for new data.
I just don't want people to run to their local auto parts store and pickup something that
a.) isn't designed for our cars
b.) doesn't change the rwhp enough to be a significant change.
IMO chip / shortshift / suspension / exhaust / LSD / brakes / Boost or ls1 swap.... then make it look pretty.
