BMW G20/G21/G28 M340i Upgraded Aluminum Turbo Chargepipe Set – Full Metal Design for Improved Reliability & Turbo Response | Fits 3 Series Sedan & Touring (B58 Gen 2 Engine, 2019–Present)

Unleash the full potential of your BMW 340i with the BAVMODS® Upgraded Aluminum Chargepipe — engineered to eliminate boost leaks, improve turbo response, and handle any power you throw at it.

The B58TU engine powering the G20, G21, and G28 3 Series is a masterpiece of modern BMW engineering — but the factory plastic chargepipe remains its Achilles’ heel. Under repeated heat cycles and boost pressure, the thin composite material is prone to cracking, splitting, or bursting, especially on tuned or aggressively driven cars. The result? Boost leaks, limp mode, and lost performance.

The BAVMODS® Upgraded Aluminum Chargepipe Set solves this permanently.

CNC-bent from high-strength aluminum and finished in a sleek matte-black powder coat, these pipes are designed to outperform and outlast the OEM setup while maintaining a clean, factory-plus appearance.

Engineered for the B58TU Powerhouse

The B58TU’s high-flow turbo and integrated water-to-air intercooler system demand boost stability and efficient airflow. This chargepipe upgrade is engineered to meet those demands with precision.

• Full-Metal Construction: Aircraft-grade aluminum eliminates flexing, cracking, and expansion under pressure.
• Improved Boost Integrity: CNC-machined flanges and reinforced couplers create a 100% airtight seal — no leaks, no CELs.
• Enhanced Throttle Response: Smooth internal surfaces maximize airflow velocity, reducing lag and sharpening turbo spool.
• High-Temperature Durability: Built to withstand the heat of spirited or track driving without warping or fatigue.
• OEM+ Fitment: Perfectly aligns with factory mounting points, sensors, and intercooler connections for an effortless, bolt-on install.

Complete Plug-and-Play Installation Kit

Everything you need for a professional-grade installation is included — no last-minute hardware runs.

Includes:

• Premium 4-ply silicone couplers
• Stainless-steel T-bolt clamps
• O-rings, push clips, and seals
• Pre-welded fittings and all required hardware

This is a true plug-and-play upgrade, designed to fit exactly like OEM while performing far beyond it.

Why Aluminum Over Plastic?

BMW’s stock composite chargepipes were designed for comfort and emissions compliance — not sustained high-boost operation. Over time, plastic expands, contracts, and weakens at the throttle-body joint until it fails.

When it does, your car immediately loses boost and triggers a “Charge Pressure Control” or “Boost Leak” fault.

The BAVMODS® Aluminum Chargepipe Set removes that failure point entirely.

Built to withstand higher boost levels, elevated heat, and long-term stress, it’s the definitive solution for anyone running a tune, upgraded turbo, or simply wanting long-term reliability.

Performance You Can Trust

This isn’t just a cosmetic upgrade — it’s a vital reliability mod for every G-chassis 340i.

Whether you’re running a factory tune or a full Stage 2+ setup, boost consistency is key to dependable power.

The BAVMODS® Upgraded Aluminum Chargepipe Set ensures your B58TU engine delivers the same relentless performance pull after pull — the same power on the 100th run as it did on the first.

Your B58 deserves confidence, not compromise.

FITMENT: BMW 3 Series – G20 Sedan / G21 Touring / G28 LWB (2019–Present) with B58B30O1 (B58 Gen 2 TwinPower Turbo Inline-Six) Engine.
