Ramair Carbon Fibre Air Intake Kit for BMW M5 (G90) 2024+
The BMW M5 G90 is already a serious performance car, but like most modern vehicles, it leaves some room for improvement under the bonnet. The factory airbox is designed with a balance of noise, emissions, and packaging in mind – not outright performance. This carbon fibre intake kit from Ramair addresses that by replacing the standard setup with a freer-flowing system built specifically for the 4.4-litre twin-turbocharged V8 (S68 engine) found in the latest M5 models from 2024 onwards.
Ramair is a UK-based manufacturer with a strong reputation in performance air filtration and induction systems. This kit is engineered to fit the G90 M5 precisely, using premium materials throughout.
What It Does and Why It Matters
The standard airbox restricts how freely air can reach the engine. By replacing it with larger carbon fibre intake pipes and high-flow Proram pleated filters, this kit reduces that restriction – allowing the twin turbos to breathe more easily. Better airflow into the engine generally means sharper throttle response, improved turbo spool (how quickly the turbos build boost pressure), and a more engaging induction sound as you accelerate.
The carbon fibre heat shields are an important part of the design. They help isolate the intake filters from engine bay heat, because cooler, denser air contains more oxygen and helps the engine work more efficiently. The shields are also bespoke to this application, meaning they integrate with the factory air feed points rather than sitting loosely in the engine bay.
What’s Included
- 2x carbon fibre heat shields
- 2x Proram pleated high-flow air filters (washable and reusable)
- 2x oversized carbon fibre intake pipes
- Silicone couplers and all required fixings
- Comprehensive fitting instructions
The Proram filters included are a pleated cotton gauze design – this style offers a good balance between airflow and filtration. They can be cleaned and reused using the Ramair CK-003 service kit, rather than being replaced each service, making them a cost-effective long-term choice.
Realistic Expectations
An intake kit like this is primarily felt through improved throttle response and a more characterful engine note, particularly as the turbos spool under load. Outright power gains from an intake alone on a modern turbocharged engine are typically modest unless paired with an ECU remap (an adjustment to the engine’s management software). If you are planning a remap, upgrading the intake first is a sensible step.
Fitment
This kit is designed for the BMW M5 fitted with the 4.4-litre twin-turbo V8 S68 engine, covering G60, G68, and G90 chassis variants from 2024 onwards.
