A complete bolt-on dual-airbox intake for the S58-powered G8X M3 and M4, engineered to open up the factory intake tracts and let each turbo draw cooler, less restricted air. It is a full kit with everything needed to fit, runs safely on the stock ECU with no tune required, and goes on in under an hour without pulling the front bumper or undertray.
Measured on the bench, it brings intake restriction down by 13% on the driver side and 22.8% on the passenger side, freeing up real power potential. Each side breathes through a high-flow oiled filter with more surface area than the stock panel element, and two extra ducts route cool air in from the wheel wells. The payoff you hear is a more aggressive intake tone under throttle, with turbo spool and bypass valve venting noticeably louder. CNC-machined aluminium connectors seal the joins for a leak-free, durable install, and the oiled filters are washable and renewable with the Mishimoto Filter Re-Oil Kit, so they last the life of the car.
