BMW G20/G21/G28 3 Series M340i Rainbow Titanium Metal Charge Pipe Upgrade Kit – Fortified Reliability, High-Strength Metal, Improved Throttle Response & Heat Resistance | Fits 2020–2025 (B58 Gen 2 / B58TU Engine)

Add a new level of performance and beauty to your BMW G20/G21 M340i with the BAVMODS® Rainbow Titanium Metal Charge Pipe Upgrade Kit, precision-engineered for vehicles equipped with the B58 Gen 2 (B58TU) engine.

The factory-installed plastic charge pipe is a well-known weak point on the B58TU platform — prone to cracking, separation, or blowing apart under sustained boost pressure. The BAVMODS® Titanium Charge Pipe replaces this vulnerable component with a fortified, high-strength metal design, ensuring maximum reliability while transforming your engine bay with a stunning iridescent rainbow titanium finish.

This eye-catching finish reflects heat while showcasing a color-shifting gradient that radiates performance and craftsmanship. Inside, the precision-machined smooth bore enhances airflow and reduces turbulence, providing faster turbo spool, crisper throttle response, and more stable boost pressure under all driving conditions — from daily commutes to spirited performance runs.

Built for both stock and tuned applications, this upgrade represents the perfect fusion of engineering excellence and visual artistry.

Key Features & Benefits

• High-Strength Metal Construction – Replaces the OEM plastic charge pipe to eliminate cracking and boost loss under pressure.
• Rainbow Titanium Finish – Heat-treated for color stability and durability, creating a stunning multi-tone effect under the hood.
• Optimized Internal Flow – Smooth interior walls promote efficient charge air movement for improved turbo response.
• Boost-Tested Reliability – Proven to withstand elevated boost levels and high-temperature cycling.
• OEM+ Fitment – Direct bolt-on replacement using factory clamps, couplers, and sensors.

• Engine Bay Enhancement – Instantly upgrades your M340i’s visual presence with a premium, motorsport-inspired aesthetic.

Performance You Can Feel

Expect immediate gains in throttle precision, boost consistency, and turbo response. The rigid titanium-coated body eliminates flex or deformation under high pressure, maintaining smooth airflow between the turbo and intercooler. The titanium material also helps reduce heat soak, ensuring your B58TU engine performs consistently across long drives and repeated pulls.

Beyond performance, the rainbow titanium finish is a statement of individuality and craftsmanship — a functional piece of art that sets your engine bay apart.

Why It Matters

Your charge pipe is one of the most critical components in your turbo system. When the factory plastic pipe fails, it can cause sudden boost loss, poor drivability, and limp mode. The BAVMODS® Rainbow Titanium Metal Charge Pipe permanently solves this issue, delivering stronger performance and reliability with a design that looks as impressive as it performs.

It’s durable. It’s functional. And it’s unapologetically beautiful — built to perform, designed to impress.
