Mishimoto has developed a performance air intake engineered specifically for the 2001–2006 BMW E46 330i. This E46 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, and the free-flowing design amplifies engine induction sounds. The stock E46 intake duct is utilized to provide cool airflow to the high-flow Mishimoto 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 E46 intake includes a steel heatshield with pre-assembled rubber trim to keep hot engine air out and help draw cold outside air in. This unit is a complete bolt-on that functions perfectly with the stock tune and can be installed in one hour using common hand tools.
