Injen 20-22 BMW M240i/M340i/M440i/xDrive Evolution Roto-Molded Air Intake System W/ SuperNano-Web

The Injen EVO1108 Evolution Air Intake System replaces the factory airbox on B58-powered BMWs with a sealed roto-molded design for unrestricted airflow. It fits 2020-2022 BMW M240i xDrive, M340i, M340i xDrive, M440i, M440i xDrive, and 2022 M440i xDrive Gran Coupe models. Dyno testing confirms gains of 13 horsepower and 11 lb-ft of torque at the wheels.

Key Features

  • Dyno Proven Power: Delivers consistent +13 HP and +11 lb-ft torque through in-house testing on B58 engines for real track results.

  • Roto-Molded Housing: Cross-link polyethylene airbox and 3.25-inch intake tube resist heat soak and ensure sealed cold air delivery.
  • MR Technology: Patented velocity stack in the intake tube smooths airflow and produces aggressive engine note without drone.
  • Bolt-On Kit: Includes filter X-3004-WB, clamps, couplers, and brackets for complete no-cut installation with all hardware provided.

Product Notes

  • Clean and re-oil filter every 30,000 to 50,000 miles based on driving conditions for sustained performance.
  • No ECU flash or tuning needed post-installation.
  • Standard ground shipping with secure foam packaging protects components during transit.
