Description
Elevate the performance and engine bay aesthetics of your BMW B58-powered vehicle with the Forge Motorsport FMINDK50-CARBON Carbon Induction Kit. Developed as a direct replacement for OEM part numbers 13718601678, 13718605164, and 13718601682, this premium carbon fiber intake system is engineered to enhance power delivery, reduce intake air temperatures (IATs), and optimize airflow to your turbocharged engine.
Performance by Design
The B58 inline-six engine is renowned for its smooth power delivery and aggressive tone. With the FMINDK50-CARBON, you can further unleash its potential. The carefully developed intake system improves airflow efficiency while preserving drivability, offering sharper throttle response and a more pronounced induction sound—particularly under boost.
Carbon Fiber Advantage
Constructed from high-grade carbon fiber, the intake not only delivers a striking visual impact but also serves a functional role in thermal management. Unlike metal or standard plastic alternatives, carbon fiber’s low thermal conductivity helps reduce heat soak, maintaining cooler intake temperatures and ensuring more oxygen-rich (denser) air enters the combustion chamber. The result is enhanced combustion efficiency, increased power, and greater engine reliability.
Enhanced Combustion Dynamics
By decreasing IATs, the FMINDK50-CARBON enables a higher-quality air/fuel mixture, helping to keep AFRs (air-fuel ratios) in optimal ranges and promoting more complete combustion in each cylinder. This can result in increased horsepower and torque, especially under sustained load or high-performance driving conditions. In simple terms: colder air equals bigger power.
Direct Replacement Fitment
Designed with precision for a seamless fit, this induction kit directly replaces the factory airbox on multiple B58-powered BMW models without the need for modifications. It retains compatibility with stock sensor locations and mounts securely in the OEM position for easy installation.
