AFE Magnum FORCE Stage-2 Si Cold Air Intake System w/Pro DRY S Filter
This will work with all 2014-2018 BMW X5 and X6’s with the N55 motor. So all 35i engines for those years this is compatible.
Full system that utilizes factory mounting points to replace the air box and upper intake tube to greatly improve air flow and reduce intake air temps. Includes all hardware and manuals.
Very noticeable power gains with this intake system, the turbo/intake sounds are awesome. I included a screenshot of AFE’s claimed gains (+21hp and +42tq)
The kit came with one DRY filter and I purchased a back up that I never used. So one used filter that has been cleaned and one brand new never opened filter.
New price of Intake System is $450 and the spare filter is $75
Asking $300 + shipping
