Ramair Air Intake Kit with Carbon Lid BMW M2/M3/M4 3.0T (Foam Filter)

Ramair Air Intake Kit with Carbon Lid – BMW M2, M3 & M4 3.0T S58 (Foam Filter)

This intake kit from Ramair is a direct replacement for the restrictive factory airbox on BMW’s S58 3.0-litre twin-turbocharged engine. Designed specifically for the M2, M3, and M4, it improves the flow of cold air into the engine, which helps the turbos work more efficiently and can result in sharper throttle response and modest performance gains. As a bonus, you’ll hear a much more pronounced induction and turbo sound compared to the standard setup.

The standout feature here is the carbon fibre lid on each heatshield. Carbon is lightweight and looks the part when you open the bonnet, but it also plays a practical role – helping to contain cooler air around the filters and away from engine heat. Cooler, denser air is better for combustion, which is why this matters beyond just aesthetics.

What’s Included

• Carbon fibre lids for both heatshields
• Black powder-coated heatshields
• Ramair foam air filters (90mm intake diameter)
• Black silicone hoses
• Black powder-coated hard pipe
• CNC-machined turbo adapters (precision-cut components that ensure a secure, accurate fit to the turbocharger inlets)
• Full fitting kit with step-by-step instructions

The 90mm intake diameter is larger than the standard setup, reducing airflow restriction and allowing the turbos to breathe more freely. The foam filters used by Ramair are reusable and washable, so unlike disposable paper filters, they can be cleaned and re-oiled rather than replaced outright.

Sound and Performance

One of the most immediately noticeable changes after fitting this kit is the improvement in induction noise. The S58 engine is already an impressive unit, but the standard airbox muffles much of that character. With this kit fitted, you’ll hear a more aggressive intake note and turbo spool – especially noticeable under hard acceleration. Performance improvements will vary depending on whether the car has been remapped, but the kit lays a solid foundation for further engine tuning by removing an airflow bottleneck.

Fitment

This kit is designed to fit the BMW S58 3.0-litre turbocharged engine as found in the M2, M3, M4, and their Competition variants from 2020 to 2023. Please use the vehicle lookup tool on this page or check the “Vehicle Fitment” tab to confirm this kit is correct for your specific model and build before purchasing.

Installation is a straightforward process using the supplied hardware and instructions, and should be achievable at home with basic tools and mechanical confidence. No specialist equipment is required.
