Infinity Design BMW B58 Carbon Fibre Cold Air Intake
The Infinity Design Carbon Fibre Cold Air Intake for the BMW B58 engine is the result of meticulous British engineering - built for drivers who demand tangible performance, not speculation. Designed, developed, and manufactured entirely in the U.K., this intake system harnesses advanced CFD (Computational Fluid Dynamics) analysis to maximise airflow efficiency, ensuring cooler, denser air reaches the turbocharger for improved power delivery and throttle response.
Constructed from aerospace-grade pre-preg carbon fibre, the intake system delivers exceptional rigidity and minimal weight, with a flawless gloss finish that elevates any engine bay. Each component is crafted with precision to ensure a perfect OEM-style fit, using factory mounting points for a seamless installation.
Whether installed on a street-driven M140i, M240i, 340i, 440i or a tuned B58 platform, the Infinity Design intake enhances induction acoustics with a refined turbo spool and deep, resonant tone - all while maintaining factory drivability and reliability.
Key Features:
-
100% U.K. engineered, tested, and manufactured
-
Pre-preg carbon fibre construction with premium gloss finish
-
CFD-designed and dyno-validated for proven gains in power and response
-
OEM fitment for precise installation and factory compatibility
-
Enhanced induction sound and airflow efficiency
Infinity Design - When precision matters more than promises.
For the G Series B58 cars we have taken full advantage of improving the intake system with a large volume airbox combined with our venturi intake tube and high flow 170mm air filter.
Based on the the same principles as our A90 Supra intake delivering vastly improved throttle response and power throughout the rpm range.
This design strategy ensures the maximum amount of air at the lowest possible intake temperature. The final result is a stunning under bonnet appearance matched with a more eager and smoother throttle response. More torque available faster and an intake sound which is sophisticated under load.
