Description
Unlock the full potential of your BMW N54-powered vehicle with the Ramair Performance Foam Induction Kit, engineered to deliver significantly improved airflow, enhanced throttle response, and an aggressive induction sound. Designed as a direct replacement for the restrictive factory airbox, this twin-cone intake system allows your twin-turbocharged 3.0L N54 engine to breathe more freely, maximizing performance without compromising filtration.
During independent dyno testing on a Stage 2 BMW 335i N54, this intake system produced an impressive increase from 393.6 BHP to 430 BHP, resulting in a 35.7 BHP gain simply by replacing the factory airbox. While results may vary depending on vehicle modifications and tuning, the Ramair induction kit has proven to be an effective upgrade for enthusiasts seeking increased performance.
The system features dual high-performance Ramair twin-layer foam cone filters, renowned for delivering exceptional airflow while maintaining excellent filtration. Unlike traditional cotton filters, Ramair's foam technology offers superior dust-holding capacity and produces a smooth, deep induction note that's highly sought after by BMW enthusiasts.
Complementing the filters are durable black silicone inlet pipes, designed to provide unrestricted airflow while withstanding high engine bay temperatures. The kit installs using the supplied brackets, hardware, and detailed instructions for a straightforward installation.
