Mishimoto MMAI-E46-99BK Air Intake Kit for BMW E46 323i/325i/328i 99-05

Mishimoto has developed a performance air intake system specifically designed for the 1999–2005 BMW E46 323i/325i/328i. This system is safe to use with the stock tune, as it does not affect air/fuel ratios under load. This system has a unique, aggressive sound under load, and its free-flowing design amplifies the sound of the engine’s induction. Check out the video to hear the sound. The stock intake duct is used to provide cold airflow to the Mishimoto high-flow air filter, which boasts an increased filtration surface area compared to the stock paper filter. This filter can be cleaned and reused, ensuring a long service life. The system includes a steel heat shield with a pre-assembled rubber trim to prevent hot engine bay air from entering and to facilitate cold outside air into the filter. This unit is an easy installation, works perfectly with the stock tune, and can be installed in one hour with common hand tools. This performance air intake kit is also fully compatible with our silicone intake hoses. This kit includes the Mishimoto Lifetime Warranty, ensuring superior quality and craftsmanship. Direct fit for 1999–2005 BMW 323i/325i/328i. 84% increase in filter surface area compared to stock filter. Works with stock and Mishimoto intake hoses. Powder-coated heat shield prevents unwanted hot air from entering the air filter. Mishimoto Lifetime Warranty.
