Product Description

The aFe Momentum ST Cold Air Intake System (Part #50-40045R) is a high-performance, direct-fit upgrade designed for BMW X5 M (F85) and X6 M (F86) models equipped with the S63 4.4L twin-turbo V8 engine from 2015 through 2019. This intake replaces the restrictive factory airbox with a sealed housing and dual high-flow Pro 5R pre-oiled filters, delivering substantially increased airflow, improved throttle response, and measurable gains in horsepower and torque without requiring ECU tuning or modifications.

Featuring a robust roto-molded intake design and premium hardware, the Momentum ST system ensures a secure and durable installation while maximizing cool air delivery to the engine. The dual filter design allows for greater intake volume, enhancing performance under load and providing a deeper induction sound. While the system significantly enhances engine breathing and responsiveness, it is 46-state legal but not CARB compliant, so it is not approved for use in California or other CARB jurisdictions.
