Mishimoto carbon-fiber performance intake for 2021+ BMW G8X M3/M4 is a complete bolt-on kit that replaces restrictive airboxes with 3K twill carbon fiber housings and dual high-flow oiled filters. Two additional wheel-well ports increase cool-air entry while flow-bench tuning reduced restriction by 13% on the driver side and 22.8% on the passenger side. The kit improves turbo spool and bypass valve sound and includes Mishimoto’s Lifetime Warranty.
