Fit is more important than originality - I am modifying a CS to sort of ApinaB2S spec, which requires the CSI airbox. The space forward by the coil though has less room and some angles making it tough to just make something work and look decent. My fallback is to use the stock CS bracket combined with the rubber spacing buffers from the stock ac damper in order to fit, but would definitely rather just use a bracket correct for the spot
