Hello,

My car is a 2015 228i xdrive. I installed an Injen cold air intake last summer and love the noises it makes but I've noticed that my cold start and idle is a lot rougher than it used to be. Sometimes it takes almost a minute for the revs to drop after firing up the car. Has anyone else experienced this with aftermarket air intakes? Is this to be expected? Odometer is right around 110,000 kilometers (68,000 miles)

Any insight for a car dumby is appreciated
