AEM Induction 21-879C is a cold-air intake for specific BMW 230i, 330i and 430i 2.0L turbo applications. Gunmetal gray aluminum configuration and an oil-free Dryflow filter replace the restrictive factory airbox arrangement. AEM reports an estimated gain of 9 HP @ 4900 RPM for its documented test configuration. Results are not guaranteed on every vehicle.
| Years | Vehicle | Engine / application |
|---|---|---|
| 2017–2021 | BMW 230i / 230i xDrive | 2.0L turbo; exact manual |
| 2017–2020 | BMW 330i / 330i xDrive | 2.0L turbo; exact manual |
| 2017–2020 | BMW 430i family | 2.0L turbo; match coupe/Gran Coupe and drive version |
Current AEM finders extend some 230i/330i years beyond the manual. Its 2020 330i GT heading also differs from current 2019 GT xDrive listings. Match the exact chassis, body style and engine rather than transferring one model’s years to another. Later trim and GT-year details remain subject to exact confirmation.
