CTS TURBO BMW F-series M140i/M240i/340i/440i B58 GEN1 Turbo Inlet Pipe

CTS Turbo's turbo inlet pipe replaces the restrictive factory plastic component on B58 Gen1-powered BMW F-series models including M140i, M240i, 340i and 440i from 2016 to 2019. Constructed from mandrel-bent aluminium alloy, this inlet pipe eliminates the accordion-style flex section and narrow internal diameter that choke airflow to the turbocharger. The smooth, optimised design reduces turbulence and heat soak while supporting higher boost levels. Direct bolt-on fitment with all necessary hardware included ensures straightforward installation for professional workshops.
