Product Description

The Injen SP1125WB SP Series Short Ram Air Intake System is a performance-oriented upgrade engineered for 2007-2010 BMW 335i, 335xi, and 2008-2010 BMW 135i models equipped with the N54 3.0-liter twin-turbo inline-six engine. This intake replaces the factory airbox with smooth mandrel-bent aluminum tubing and a high-flow SuperNano-Web dry air filter to deliver cooler, denser air to the engine, improving throttle response and power throughout the rev range. Patented MegaRam and Air Fusion technologies optimize airflow while maintaining safe air/fuel ratios without requiring additional tuning.

Built for both performance and durability, the SP1125WB produces a more aggressive induction sound and enhances engine bay aesthetics with its wrinkle black finish. Installation is straightforward using included hardware and instructions, making it accessible for enthusiasts. Backed by Injen Technology's limited lifetime warranty, this intake is an ideal upgrade for BMW owners seeking improved airflow, throttle response, and engine character from their N54-powered 135i or 335i - just be aware that vehicles with active steering are excluded. Always verify local emissions requirements before purchase, as CARB EO may vary by model year and region.
