FTP Motorsport are market leaders in the field of upgraded BMW charge pipes and performance solutions. Each kit is specifically designed to ensure the best possible flow, fitment and protection against the failure that the OEM plastic charge pipes are renowned for.
Maximise airflow, boost response, and overall reliability on your S58-powered BMW with the FTP Motorsport S58 High-Flow Turbo Inlet Set for BMW G80/G81 M3, G82/G83 M4, G87 M2, F97 X3M and F98 X4M models. Designed specifically for the twin-turbo S58 engine platform, this upgrade eliminates key airflow restrictions found in the factory plastic inlets and delivers improved mid-range and high-RPM performance.
Engineered from aerospace-grade billet aluminium using advanced 5-axis CNC machining, the FTP inlets provide superior strength, heat resistance, and long-term durability compared to the OEM units. An enlarged internal diameter and optimised geometry reduce intake restriction, helping the turbos breathe more efficiently while sharpening throttle response and decreasing turbo lag.
Tested extensively across both street and performance applications, the FTP High-Flow Turbo Inlets integrate perfectly with the OEM airboxes and are fully compatible with both factory and hybrid turbochargers. No tuning is required — with gains of up to 12 hp and 23 Nm recorded on a stock G80 M3 with this upgrade alone.
Unlike cheaper alternatives, FTP Motorsport products are precision-engineered for perfect fitment and proven durability. Each component is designed to meet OEM tolerances, ensuring hassle-free installation and long-term reliability even under high boost conditions.

Excellent service at reasonable prices. The shop is very nice too, you almost feel like you're at BMW.

Sean arranged a Quaife LSD for my 135i and I couldn't be happier. He advised multiple seals and bearings needed replacing unbeknownst to me so these were done as well. Now I have a more reliable car and one with tonnes more mechanical grip!
