Introduction
Performance cold air intake for BMW 328I. High‑flow reusable filter with full heat shield box, improve airflow & throttle response, direct bolt‑on upgrade.
Product Overview
Upgrade your BMW 328I with this complete cold air intake system. The restrictive factory air box limits incoming air volume and draws in hot under‑hood air, hurting engine performance. This cold air intake is equipped with a high‑flow reusable red conical air filter and full metal heat shield. The heat shield isolates the filter from high‑temperature engine‑bay heat, delivering denser cooler air into the engine. Enlarged intake tube reduces air flow resistance, brings improved throttle response, better engine sound and noticeable power gain. Pre‑drilled mounting holes match OEM positions for bolt‑on installation without cutting or drilling. A simple and cost‑effective performance modification for BMW 328I.
