Product Description

The aFe 54-31662-C Magnum FORCE Stage-2 Carbon Fiber Cold Air Intake System with Pro 5R filter is a high-performance induction upgrade specifically designed for BMW M3 E90, E92, and E93 models equipped with the 4.0L S65 V8 engine. This system replaces the stock intake components with a lightweight carbon fiber intake tube and a high-flow, washable Pro 5R oiled filter, substantially increasing airflow and enhancing throttle response. The unique cold air design uses the factory intake box seal to help reduce heat soak and maximize dynamic airflow into the engine. Performance figures are approximate and may vary by vehicle and conditions.

Installation is straightforward with a direct bolt-on design that requires no cutting or drilling, and the included billet aluminum smog pump adaptor ensures correct factory fitment. The carbon fiber tube not only reduces weight compared to standard materials but also adds a premium aesthetic under the hood. This intake system is ideal for enthusiasts seeking enhanced power and engine sound while maintaining a clean, factory-integrated look. Fitment is confirmed through the 2013 model year; coverage beyond this is unconfirmed at the time of listing. Always verify compliance with local emissions regulations, as this product may not be legal in all regions.
