Performance Air Intake For BMW E46 1999–2005




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 air filter. The intake includes a steel heat shield 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 upgrade that functions perfectly with the stock tune and can be installed in one hour using common hand tools. This kit includes the Mishimoto Lifetime Warranty, ensuring superior product quality and craftsmanship.
