Product Description

The Injen SP1140WR SP Series Short Ram Cold Air Intake is a direct-fit performance upgrade designed for BMW models equipped with the B58 3.0-liter turbocharged inline-six engine, including M240i, M340i, and M440i variants from 2020 through 2025. This intake system replaces the stock airbox with an oversized 4.00" mandrel-bent T6-6061 aluminum tube and a high-flow SuperNano-Web dry air filter to improve airflow into the engine, enhancing throttle response and overall performance. Because it works with the stock ECU tune, it delivers gains of up to approximately 19 hp and 18 lb-ft of torque without requiring additional software modifications.

Finished in a striking wrinkle red powder coat with a custom heat shield, the SP1140WR also produces a more aggressive induction sound under acceleration and adds visual appeal to your engine bay. The intake system comes complete with all necessary hardware and installation instructions, and it's backed by Injen Technology's limited lifetime warranty for long-term reliability. Note that this intake is not currently CARB exempt and may be restricted in certain states - always check local emissions requirements before purchase.
