Dinan Cold Air Intake – 2020–2025 BMW X3M / X4M (F97/F98)

Extract more performance from your 2020–2025 BMW X3M or X4M with the Dinan Cold Air Intake — a precision-engineered intake upgrade developed specifically for the F97/F98 S58 engine platform. Dinan's engineering approach on the X3M/X4M was honest and deliberate: despite its unorthodox appearance, the OEM intake system is remarkably efficient given its packaging constraints. Rather than a wholesale redesign that would compromise packaging or price, Dinan targeted the most restrictive element in the factory system — the filters themselves. Replacing the stock paper filters with Dinan's multi-layered cotton filters increased airflow by nearly 20%, delivering measurable power gains in the mid and upper RPM range where the S58 makes its power, while also transforming the engine bay with a visual upgrade worthy of the X3M/X4M's performance credentials.

Key Features

• ~20% Increased Airflow: Dinan multi-layered cotton filters increase airflow by nearly 20% over the stock paper filters — a significant improvement that directly translates to power gains in the mid and upper RPM range
• Mid & Upper RPM Power Gains: Measurable power gains in the mid and upper RPM range — where the S58 biturbo inline-six makes its power and where X3M/X4M drivers spend their time on track and spirited road driving
• Multi-Layered Cotton Filters: Dinan's multi-layered cotton filter design provides superior filtration and airflow compared to OEM paper filters — washable and reusable for long-term cost savings and consistent performance
• Engineered for OEM Packaging: Designed to work within the X3M/X4M's tight engine bay packaging constraints — a direct, targeted upgrade that improves the most restrictive element of the factory system without compromising fitment or reliability
• Visual Engine Bay Upgrade: Transforms the engine bay with a visual upgrade that matches the X3M/X4M's performance character — a meaningful improvement over the stock intake's utilitarian appearance
• Dinan Quality & Expertise: Manufactured by Dinan — the leading BMW performance tuning brand in North America, with decades of BMW-specific engineering expertise and a reputation for reliability on street and track
