Product Description

The Injen SP1129WB SP Series Short Ram Air Intake System is a performance-oriented upgrade engineered for a range of BMW models powered by the B58 3.0 L turbocharged inline-six engine, including M140i, M240i, 340i, and 440i variants from 2016 through 2021. This intake replaces the restrictive factory intake path with mandrel-bent aluminum tubing and a high-flow SuperNano-Web dry air filter to improve airflow into the engine. The result is enhanced throttle response and power delivery without requiring additional tuning.

Featuring Injen's patented MegaRam and Air Fusion technologies, the system helps maintain safe air/fuel ratios even at elevated airflow levels. The included custom heat shield is tailored to the B58 intake layout, helping reduce intake air temperatures for better performance potential. The wrinkle black finish adds a sleek look to the engine bay, and the intake produces a more aggressive induction sound under acceleration. Installation is straightforward with bolt-on hardware and instructions included. Backed by Injen Technology's limited lifetime warranty, the SP1129WB is ideal for BMW enthusiasts seeking improved performance and engine character. Always verify local emissions requirements, as this part is not currently CARB exempt in all regions.
