Upgrade your BMW with the Injen SP1140WB Cold Air Intake System, engineered specifically for models from 2020 to 2022 including the M240i, M340i, and M440i. Crafted from massive 4.00-inch O.D. 6061-T6 mandrel-bent aluminum tubing, this intake provides a smooth, unrestricted airflow path that enhances engine performance and responsiveness. The polished and wrinkle black finish options give your engine bay an aggressive, high-performance look while maintaining perfect OE fitment. This system is designed to deliver significant power gains, with dyno-proven increases of up to 19 horsepower and 18 lb-ft of torque, providing you with noticeable throttle response and engine tone under full throttle conditions. The included custom heat shield helps protect the intake from under-hood heat, ensuring optimal airflow and performance. The fully serviceable Injen SuperNano-Web dry air filter maintains filtration quality while supporting maximum airflow. Installation is straightforward and does not require additional tuning when paired with your stock ECU, making it a convenient upgrade for enthusiasts seeking quick, reliable power improvements. Suitable for daily drivers and performance enthusiasts, this intake system combines durability, style, and performance in a package made in Pomona, California, USA, backed by Injen's limited lifetime warranty.
