I've sold my 2014 X1 28i, and have the AFE Cold Air Intake (part # 54-12522) available for sale. This intake only fits the E84 X1 S/XDrive28i.
Asking $200 (paid $450)
Excellent condition. Local cash pickup only in Tustin/Irvine, CA area.
I also have the AFE Scorcher available for $180. If you buy both the intake, and scorcher, I'll both parts for $340. Add a real 40hp/40 torque for $340.
Thank you
