Carbon Cold Air Intake System w/ K&N Filters

This snorkel draws in cooler air from a low-pressure zone behind the front bumper, reportedly up to 40 degrees cooler than the factory inlet location. The system utilizes two K&N filters: a panel filter within the stock airbox and a cone filter on the new snorkel, offering a less restrictive airflow. Dinan claims peak gains of 5 horsepower and 6 ft-lbs of torque from this intake alone, with more significant benefits realized at higher RPMs where increased airflow is crucial. For optimal performance, Dinan recommends accompanying this intake with their performance software. The carbon fiber construction not only enhances the engine bay's aesthetics but also benefits from the material's superior thermal resistance. This intake system is designed for specific BMW models including the 2008-2010 E82/E88 135i, 2007-2008 E90 335i/xi, and 2007-2010 E92/E93 335i/is models.
