Description
The Injen SP1140WR Short Ram Air Intake System is engineered to enhance performance and aesthetics for select BMW models including the M240i, M340i, and M440i from 2020 to 2022. Crafted from massive 4.00-inch O.D. T6-6061 aluminum tubing, this intake provides a smooth, mandrel-bent pathway that minimizes restrictions and maximizes airflow efficiency. The result is a noticeable increase in horsepower and torque, with dyno tests indicating gains of up to 19 horsepower and 18 lb-ft of torque, delivering more responsive acceleration and a pronounced engine tone under full throttle. The intake’s aggressive yet refined appearance enhances the engine bay’s visual appeal while maintaining an OE fit and finish, making it a compelling upgrade for enthusiasts seeking both form and function.
Designed with durability and ease of installation in mind, the system includes a custom heat shield tailored specifically for these models, ensuring optimal thermal management. The fully serviceable Injen SuperNano-Web dry air filter ensures long-term filtration performance, while the system’s design allows it to work seamlessly with the stock tune, eliminating the need for additional tuning. Available in Wrinkle Red, Polished, and Wrinkle Black finishes, this intake system complements various aesthetic preferences and adds a bold statement under the hood. Manufactured in Pomona, California, and backed by Injen’s limited lifetime warranty, the SP1140WR represents a high-quality upgrade that combines performance gains with an aggressive engine tone and a robust build quality.
Note that this product is not currently CARB exempt and is not legal for use in California or on any vehicle registered there. Optional Hydroshield covers are available to provide extra protection for the intake system.
