*N63/S63: Red coils purchased after 9/1/2022 will not require modification but for coils purchased prior to this some N63/S63 applications may require a minor modification (removal) of a small molding rib below the connector for proper fitment (~MY2016+). See FAQ under the Tech Resources section below to determine if your vehicle would require this modification for fitment. Once modified the coils are not returnable so please do so at your own risk.
