Infinity Design BMW S55 Carbon Fibre Cold Air Intake
Designed and manufactured entirely in the U.K., the Infinity Design Carbon Fibre Cold Air Intake for the BMW S55 engine (F80 M3, F82/F83 M4, F87 M2) is built for precision, performance, and uncompromising quality. Every system is the result of extensive CFD (Computational Fluid Dynamics) development and dyno validation - ensuring measurable gains in airflow efficiency, power delivery, and throttle response.
Constructed from aerospace-grade pre-preg carbon fibre, this intake system achieves the perfect balance between strength, weight, and heat resistance. Its dual high-flow filters and optimised carbon housings deliver cooler, denser air directly to the twin turbochargers, unlocking sharper throttle response and a more pronounced induction tone.
Every component has been designed for OEM-level fitment, utilising factory mounting points for a seamless installation. The result is a refined, performance-driven upgrade that not only enhances performance but transforms the engine bay with its flawless gloss carbon finish.

Infinity Design - Engineering performance, not promises.
The S55 intake system is the result of extensive analysis and testing.
The design is fully sealed with no gaps to ensure the lowest air intake temperatures.
The primary focus has been to keep the air flow as smooth as possible as well as
In order to improve on the OEM system we have used the maximum space available to create the largest intake on the market.
A detailed and accurate design with air filter housings connect directly to the OEM air feeds.
Both banks having large cross sectional turbo inlet tubes with integrated MAFs with smooth expanding inlet tubes
The expanding large volume inlet tube acts like a large velocity stack which accelerates the airflow and is much larger than the small and short velocity stack fitted to the internals of the oem intake.
The result of the smoother airflow from our inlet tube is a far smoother lower rpm torque availability from the engine vastly improving drivability. Throttle response is immediately felt to be smoother and more eager. The inlet tubes are attached via a stainless steel v-band clamps to the air filter housings which attaches directly to the OEM front air feeds.
