Mishimoto has developed a performance air intake engineered specifically for the 2012 BMW F30 w/ N20 engines! This Performance Air Intake is safe to use with the stock tune as it will not hurt air/fuel ratios under load. This intake has a unique and aggressive tone under acceleration and boost, and the free-flowing design amplifies turbocharger spool and BPV sounds. Check out the video to hear the tone. The stock intake duct is utilized to provide cool airflow to the Mishimoto High-Flow Oiled Air Filter, which features increased filtration surface area compared to the stock paper filter. This filter can be cleaned and reused, providing a lifetime of service. The intake includes an enclosed airbox that collects all of the cold outside air from the front of the engine. The airbox is made from 5052 aluminium with a black powder-coated finish to reduce weight compared to a steel intake box, and to prevent against any corrosion. The airbox also protects against engine bay heat-soak, and it provides a unique engine bay appearance. This unit is a complete bolt-on that functions perfectly with the stock tune. This kit includes the Mishimoto Lifetime Warranty, ensuring superior Products quality and craftsmanship.
