BMW G Series B58TU (Gen 2) 4 Inch/102mm Turbo Inlet Elbow Pipe - High-Flow Intake Pipe, Induction/Suction Tube, Compressor Inlet Upgrade for Faster Spool, Lower Wastegate Duty (WGDC) & Stronger Mid-Range

BMW G Series B58TU Large-Bore Intake Elbow, 4 inch Free-Flow Inlet Pipe

Unleash your BMW G Series B58 Gen 2 with a big-bore intake elbow that lets the turbo breathe properly. This 4 inch, free flowing inlet pipe feeds the compressor with a straighter, higher volume path, giving you crisper pedal response, earlier boost, reduced wastegate effort and a fatter, more usable midrange. Perfect on a standard map and even better on tuned cars, it is a simple bolt-on that removes intake restriction and unlocks headroom for future upgrades.

What makes it a must-have on B58TU

• Large diameter, de-restricted design for maximum airflow to the compressor inlet
• Noticeably sharper transient response and quicker boost build
• Lower wastegate command for improved turbo efficiency and consistency
• Stronger mid band torque for punchy real-world acceleration
• Rock solid foundation for remaps, intercooler and high-flow filter upgrades

Proven on our builds
