A gloss carbon fibre intake for the S58-powered G8X M3 and M4, cutting intake restriction by 13% on the driver-side tract and 22.8% on the passenger side for more power potential, while sharpening the intake experience. It runs safely on the stock ECU tune and installs in under an hour without removing the front bumper or undertray.
The dual carbon airboxes feed each turbo through high-flow oiled filters with more surface area than the stock panel filters, and two extra fresh-air ducts pull cool air from the wheel wells. Beyond flow, the system noticeably amplifies turbo spool and bypass valve venting, adding to the drive. CNC-machined aluminium connectors keep the joins leak-free and durable, and the oiled filters are washable and re-oilable with the Mishimoto Re-Oil Kit for a lifetime of use.
