Injen Evolution Roto-Molded Air Intake System with SuperNano-Web for 2020-2025 BMW M240i/M340i/M440i (EVO1108)

Fits select 2020-2025 BMW M240i, M340i, and M440i models, including xDrive and Gran Coupe variants equipped with the Turbo B58 or Turbo Hybrid B58 engine.

The Injen Evolution cold air intake system (EVO1108) is a performance induction upgrade engineered to replace the restrictive factory airbox. Constructed from high-strength cross-linked polyethylene (XLPE) roto-molded plastic, this system provides a durable thermal barrier against engine bay heat soak while maintaining a factory-clean appearance. The intake box integrates seamlessly with the original equipment (OE) air scoop to capture the maximum volume of cool ambient air, delivering dyno-proven gains of up to 13 hp and 11 lb-ft of torque.

This system utilizes Injen’s patented TwistLock method to secure the 5.00" I.D. SuperNano-Web dry air filter, eliminating the need for additional hardware while ensuring an airtight seal. Designed to work with the factory ECU calibration, the Evolution intake provides an aggressive engine growl under acceleration and improved throttle response without requiring a custom tune.
