X5 Charcoal Intake Air Filter Delete?
Couldn't find anything about this using search so thought I'd ask...
Are North American F15 X5s factory equipped with a secondary charcoal filter in the air intake? (not the charcoal cabin air filters). Other BMW models have it in North America for emission purposes to limit vapors from coming out of the car when it is turned off. Charcoal intake air filter delete is a common mod to supposedly improve throttle response. Thanks...

From my experience the 50i and X5M do not have it. I haven't played with the 35i so I don't know.
The e70 X5M had it... I removed it. Did not notice a difference but never put them back.

Thanks. I'm running an sDrive35i.
I performed this mod on an F01 7 series and "think" I detected a slight improvement.

35i doesn't have charcoal filter.
They only use that on the N63 engines.
