BMW E46 1999–2005 Mishimoto Performance Air Intake
Mishimoto has developed a performance air intake engineered specifically for the 1999–2005 BMW E46 323i/325i/328i. This 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 load, and the free-flowing design amplifies engine induction sounds. Check out the video to hear the tone.

The stock 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 intake includes a steel heatshield with pre-assembled rubber trim to keep hot engine air out and help draw cold outside air into the filter. 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. This performance air intake kit is also fully functional with our silicone intake hoses as well. This kit includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
