Injen SP1121BLK Short Ram Air Intake System with SuperNano-Web Dry Filter

The Injen SP1121BLK is a performance short ram air intake system engineered to deliver measurable power gains for BMW N52 3.0L inline-six engines. This system replaces the restrictive factory airbox with a precision-mandrel bent 6061-T6 aluminum intake tube that provides a smooth, unobstructed path for maximum airflow to your engine.

Performance and Technology:

Dyno-tested results show gains of up to 12 horsepower and 11 lb-ft of torque while maintaining safe air/fuel ratios throughout the power band. The SP1121BLK incorporates Injen's patented MegaRam (MR) Technology and Air Fusion Technology—innovations protected by four separate patents that optimize intake tuning for maximum performance. No additional tuning or programming is required for installation.
