Mishimoto Induction Kit / Cold Air Intake CAI for BMW E46 330i 330ci 330xi 3.0 M54 (2001-2006) - Performance Airbox Delete with Heat Shield Cone Filter - Black - MMAI-E46-01BK

Mishimoto E46 3 Series 3.0 Induction Upgrade – MMAI-E46-01BK

Give your straight-six the breathing room it deserves. This Mishimoto induction system transforms the airflow path on the E46 330 models, replacing the restrictive factory airbox with a freer flowing setup and a quality heat shielded filter in a stealthy black finish. Expect a sharper throttle feel, a deeper intake note and proven gains on a standard calibration, all while keeping reliability intact.

Highlights that enthusiasts care about

• Measured improvements: up to 7 wheel horsepower and 9 lb‑ft at the wheels on a stock car
• No remap required – works perfectly on the factory calibration
• Throatier induction sound that lets the 3.0 straight‑six sing without drone
• Straightforward bolt‑on fitting with basic tools, typically around 60 minutes
• Reusable oiled cone element with large surface area for excellent filtration
• Black powder coated steel shroud helps keep hot under‑bonnet air away from the filter
• Retains the OE front air feed and pairs neatly with optional Mishimoto silicone hoses
• Backed by the Mishimoto Lifetime Warranty for total peace of mind

Why this upgrade works

The stock E46 3.0 intake tract features convoluted ducting and a closed airbox that can hinder flow. Mishimoto’s smooth 3.5 inch silicone inlet draws cool ambient air from the original front snorkel into a high‑flow oiled filter, while the robust heat shield helps isolate it from engine bay temperatures. The result is cleaner, less restrictive airflow, a livelier response and real gains you can feel and hear.
