How it works
The factory E46 airbox and convoluted ducting can limit airflow. Mishimoto’s free‑flowing intake tract and 3.5 inch silicone inlet draw cool air from the stock front duct into a high‑flow oiled filter, while the powder‑coated steel heat shield helps isolate intake air from under‑bonnet heat. The result is improved breathing, a sharper induction note and real, measured gains on a stock car.
