BMW F30/F31/F34/F35 3 Series 340i Aluminum Turbo Inlet Pipe Upgrade – High-Flow Design, Fortified Reliability, Improved Turbo Response & Heat Resistance | Fits 2015–2019 (B58 Gen 1 Engine)

Unleash your 3 Series’ true breathing potential with the BAVMODS® Aluminum Turbo Inlet Pipe Upgrade, precision-engineered for F30, F31, F34, and F35 340i models equipped with the B58 Gen 1 engine.

From the factory, BMW equips these vehicles with a plastic turbo inlet that restricts airflow and can weaken under high heat or elevated boost pressure. The BAVMODS® High-Flow Aluminum Turbo Inlet solves this problem with a rigid, precision-machined metal design that enhances both durability and performance.

By optimizing the internal airflow path, this upgrade reduces turbulence and restriction, allowing your turbocharger to spool faster and operate more efficiently. The result is improved throttle response, quicker boost delivery, and smoother power transitions across the RPM range.

Finished in a sleek matte black coating, it not only improves performance but also adds a professional, OEM+ look to your engine bay — perfect for enthusiasts who value both reliability and refinement.

Whether your goal is improved drivability or maximum performance under tune, the BAVMODS® Aluminum Turbo Inlet Pipe is the ideal solution to keep your B58-powered 3 Series breathing freely and performing flawlessly.

Key Features & Benefits

• High-Strength Aluminum Construction – Replaces weak OEM plastic to prevent cracking, distortion, and boost leaks.
• Optimized Airflow Geometry – Enlarged, smooth-flow interior reduces restriction for faster turbo response.
• Enhanced Boost Efficiency – Promotes more consistent pressure across the turbo system.
• Improved Throttle Feel – Sharper pedal response and stronger mid-range power.
• Matte OEM+ Finish – Clean, heat-resistant coating enhances engine bay presentation.
• Direct Bolt-On Installation – Uses factory fittings, clamps, and connections.
• Tuned or Stock Compatible – Perfect for both daily and performance builds.

Performance You Can Feel

The BAVMODS® Turbo Inlet Pipe transforms how your 3 Series responds to throttle input. Expect faster turbo spool, reduced lag, and more stable boost delivery even under high-demand driving. The rigid aluminum design eliminates flex and airflow inconsistency, giving your B58 turbocharger the consistent feed of air it needs to perform at its best.

Pair it with a high-flow intake or tune, and you’ll experience an immediately sharper, more responsive feel behind the wheel.

Why It Matters

The factory turbo inlet pipe is one of the most overlooked restrictions in the B58 intake system — and one of the weakest under heat and pressure. When it fails, it can cause erratic boost behavior or air leaks that hurt performance.

The BAVMODS® Aluminum Turbo Inlet Pipe eliminates that risk entirely, combining durability, efficiency, and design precision in one essential upgrade. It’s functional, reliable, and visually clean — built to outperform OEM in every way.
