Product Description

The aFe Power 50-70083R Momentum GT Cold Air Intake is a performance-focused direct-fit intake upgrade for BMW M-series models equipped with the high-output 3.0L S58 twin-turbo inline-six engine (found in M2 G87, M3 G80, and M4 G82/G83 from 2021 through 2024). Designed to replace the restrictive factory airbox, this intake significantly increases airflow - up to ~43% more than stock - which can translate into noticeable gains in horsepower and torque, sharper throttle response, and improved engine efficiency.

Featuring a pre-oiled Pro 5R radial flow filter system with five layers of high-performance cotton gauze media and a patented one-piece housing, the 50-70083R simplifies installation while maximizing airflow. The clear sight window allows for quick visual inspection of the filter without removal, and the durable XLPE construction resists heat soak, preserving cooler intake temperatures. Installation is straightforward using existing factory mounting locations, and premium hardware ensures a secure fit. This intake is ideal for BMW M-car enthusiasts seeking enhanced performance on the street or track. Note: This product is not currently CARB exempt and cannot be registered in California or equivalent emissions states.
