Product Description

The aFe 51-82952-C Magnum FORCE Stage-2Si Cold Air Intake System with Pro DRY S filter is a performance-oriented, direct-fit intake upgrade developed specifically for the BMW M3 (E90/E92/E93) powered by the S65 4.0L V8 engine. This sealed intake replaces the restrictive factory airbox with a custom CAD-designed roto-molded housing and dyno-tuned intake tube that deliver significantly increased airflow - up to approximately 50 % more than stock - helping enhance throttle response, engine sound, and overall performance. The included Pro DRY S synthetic air filter is oil-free, washable, and reusable, offering a blend of high flow and long-lasting filtration with minimal maintenance.

Featuring a carbon-fiber look ABS trim cover for an enhanced underhood appearance and a built-in resonance chamber to reduce unwanted intake noise, this Magnum FORCE Stage-2Si intake installs easily using existing factory mounting points with no cutting or drilling required. The system is CARB 50-state legal under EO# D-550-38, making it compliant for use in emissions-controlled states. With an estimated performance increase of up to roughly +6 HP and +6 lb-ft of torque, this intake is a great bolt-on upgrade for BMW M3 enthusiasts seeking improved airflow and engine responsiveness while maintaining emissions compliance.
