Product Description

The Mishimoto MMAI-G80-21 Performance Air Intake Kit is a high-quality upgrade designed for use on 2021 and newer BMW G8X-series M3 and M4 models, as well as the G87 M2 equipped with the potent 3.0-liter S58 twin-turbo inline-6 engine. This complete bolt-on intake replaces the restrictive factory intake system with precision-engineered rotational-molded airboxes and high-flow filters to reduce restriction and increase airflow for improved engine response and performance. The twin intake design draws cooler air from additional wheel well ducts, helping deliver denser air for combustion efficiency and richer induction sound.

Featuring durable construction and CNC-machined connectors for a secure fit, this intake system improves turbocharger response and bypass valve sound without requiring ECU tuning on stock engine management. The passenger-side turbo inlet enhances flow and overall reliability, while the simple bolt-on installation saves time and effort. Included Mishimoto Lifetime Warranty coverage ensures long-term confidence in the product's performance and durability.
