Mishimoto 2021+ BMW G8X M3/M4 Performance Intake Carbon Fiber Matte

Mishimoto's carbon fiber performance intake for the 2021-2025 BMW M2, M3, and M4 (G8X platform) is built from solid 3K twill-woven carbon fiber with a matte finish that gives the engine bay a clean, understated look. Beyond aesthetics, the carbon fiber construction resists heat soak from the engine compartment, helping keep intake air temperatures lower than the factory plastic airboxes.

Flow bench testing shows a 13 percent reduction in intake restriction on the driver side and a 22.8 percent reduction on the passenger side compared to stock. Two additional cold-air entry ports route through the wheel wells to pull in cooler outside air, further improving the conditions for the S58B30 twin-turbo inline-six. The dual high-flow oiled air filters included in the kit offer more surface area and improved airflow over the OEM panel filters.

Installation is a bolt-on process with all necessary components in the kit. No permanent modifications to the vehicle are required. The filters themselves are washable and reusable with Mishimoto's Filter Re-Oil Kit, which means you will not need to keep buying replacements. Owners also report noticeably louder turbocharger spool and bypass valve venting sounds after installing this system, which changes the character of the driving experience.

Mishimoto backs this intake with their lifetime warranty. Keep in mind that this is not CARB-approved, so it is not street-legal in California and other CARB-regulated states. It is best suited for track or off-road use in those jurisdictions.
